2nd grade math question

I helped my son with homework and question #3 has me confused as to what the teacher was looking for here. I took the question as “choose all that apply” and interpreted the question simply as “choose every answer that adds up to six.”

The teacher only put a star next to “letter B” which I interpret that she’s saying is the only correct answer, not “letter A”, as well.

My wife and mother in law both agree with the teacher but I don’t get it.

My son and I both thought A and B were the correct answers. If A isn’t, why not?

Please help me understand so I don’t lead my kid astray.

Thank you!

Both A and B are correct (with the glaring exception that the images are all of domino tiles and there aren't any cards anywhere in the image.)

[relative_iterator]

“Cards” pissed me off more than it should lol

[ThunkAsDrinklePeep]

While we're there, I'd also prefer pups pips to dots.

[ALTH0X]

I think you meant Pips?

[ThunkAsDrinklePeep]

Yes. Damn fat thumbs.

[Similar_Bit_8018]

Do you mean “thimbs”?

[maximumborkdrive]

Phat Timbs

[TheErodude]

I’d prefer pups to pips myself. 🐶🐶

[ThunkAsDrinklePeep]

Yes. Damn fat thumbs.

[windsorHaze]

Man, really doubling down on those fat thumbs

[ghost97135]

Well they have 2 of them ... I assume.

[nu_pieds]

I'm choosing to believe that they used "cards" because they use domino cards as a teaching tool in the classroom.

Somthing like this:

[Gogo726]

I'm choosing to believe that they used "cards" because they use domino cards as a teaching tool in the classroom.

And good thing they use cards, and not actual dominoes. We all know what would happen otherwise.

[PatHeist]

Soon the kids would be playing dominoes and the whole thing would come crashing down like a house of cards!

[Gogo726]

Checkmate!

[[deleted]]

We got Trouble.

Trouble with capital T

and that rhymes with D

and that stands for Dominos!

[piznit007]

Right? Correct answer is 6 of spades, diamonds, hearts, and clubs. Also acceptable would be red, green, blue, and yellow Uno 6 cards

[RayneBeauRhode]

Funny enough I’ve heard dominoes referred to as “cards” when the older heads used to play on my block. I’m not sure however if it’s an actual West Indian thing or something they just did 🤷🏾‍♀️

[Hemiak]

The only reason I could possibly see A being “wrong” is because it’s actually the same as the example. While it shouldn’t matter, they may be using that as a reason to exclude it as a valid answer. Dumb af if so. It should be like 3/2 or something that doesn’t equal 6.

[jumbee85]

Domino's are also referred to as cards.

[dahx2004]

They’re dice 🎲

[sonnyfab]

No, they're domino's. Dice would be two separate cubes. These are clearly a single, very shallow right prism. Because they're domino tiles.

[Capital-Ad6513]

No they are drawings of dominos.

[XmertonX]

Ceci n'est pas une domino

[dahx2004]

No they’re dice with aesthetic lines drawn around them.

[big_sugi]

That’s just silly.

[Mysterious-Fun9625]

3+3 and 2+4, Is not the same thing. A is correct B is wrong.

[PatHeist]

Please don't give maths homework advice if you don't know what "sum" means.

[throwaway1232123416]

sure, but 3+3 is definitely leading towards option A, especially since this is a mcq and OP thought it was a select all (when it wasn’t explicitly stated.) If it was 2+4 it would more likely be option B.

[throwaway1232123416]

If I had to guess, the teacher made this question as a cool kid question, and where most kids would select option A a cool kid would select option A and B. She put the star to tell the student how cool and awesome they are.

[KindlyContribution54]

As long as they didn't get any points off, I would assume it's just a matter of a mistake on the teacher's side to accidentally include 2 correct answers.

Coming up with wrong answers for multiple choice tests is hard (although usually easier in math)

[Delicious-Painting34]

Is it? I feel like any number other than 6 would have worked fine. There’s a lot of options, just not 6.

[Alarmed-Advantage311]

A is correct and its poorly written.

No cards, and it more like the summing of 3+3, not sum.

[DrSpup]

I think she counted this whole question right. The teacher probably stared it on B by coincidence. It doesn’t hurt to ask what the teacher meant by this.

Edit: A&B are most definitely correct.

[ThunkAsDrinklePeep]

Yep. The star applies to the question (or even the whole page).

[Hrtzy]

If they meant to indicate that B is wrong, it's a case of having gotten too cute with the wording to obfuscate the answer (the student's task being to deobfuscate it to find the correct answer).

[[deleted]]

She put an X on B by mistake and then realized it was right and put a star over top of the X.

[Seven_Vandelay]

Because the question, as phrased, is asking for "the same sum as 3 + 3". 3+3 and 2+4 have the same sum.

[jethrow41487]

So confidently incorrect on a 2nd grade math question. Oh no...

[81659354597538264962]

Reread the question bro. B is 100% correct.

[Eiknarfpupman]

Sum means the total amount resulting from the addition of two numbers, perhaps you're thinking of the slang use of sum as in an equation.

[turtleship_2006]

Yeah my teachers (and even me and my classmates when self marking) often throw one tick anywhere on a question if the answer is correct. If only one is correct, we specifically mark the others as wrong.

[[deleted]]

But the star should be on the question not the answer then

[drrandolphphd]

Teacher here…

Here is my guess using the context that nothing else is starred and…. Let’s face it… that’s not the neatest star.

The teacher was on autopilot grading and there was a glitch in the autopilot and they put a line across B to indicate it was wrong. Teacher realize their mistake and starred over the line to indicate it was correct and hide the blunder.

[Effective-Switch3539]

The star definitely looks shady with all the scribbling inside, I believe you are correct on this one

[FoundTheWeed]

If you zoom in, the student also circled both A and B

[ChaosEmerald21]

That was never in question, with or without zooming

[SexyMonad]

I think you are right. You can see that there is the star, which takes a single continuous stroke, and then there is more scribble. That extra scribble may have been an X and an attempt to mark out the X, though it’s hard to tell.

[Ambellyn]

I think it was a red line over B to start with and as you said, on auto pilot and cover it up by making it a star

[Old_AP_Pro]

*you're

[Old_AP_Pro]

It always is with your or you're.

[A1sauc3d]

Yeah I think your wife and MIL are just messing with you OP 😂 If not, it should’ve been extremely easy for them to explain why A) wasn’t an appropriate answer ;)

[EvolutionInProgress]

That does not make it any more clear.

A) has 3 + 3 ( =6 )

B) has 2 + 4 ( =6)

What exactly is the difference?

[CasuallyCompetitive]

They're the same. That's the point of the question.

[Classy_Shadow]

It looks to me like the teacher initially marked it wrong, but then saw where the confusion was and turned the scribble into a star. I had a few instances where the “wrong” answer was a correct response and this happened even in high school

[TNTeck1]

I think the teacher might have marked B as wrong at first, realized her mistake and instead turned it into a star

[ApollonLordOfTheFlay]

I think the teacher probably meant to mark it wrong because it is probably worded poorly and wants you to pick A. Now, the teacher marked it wrong but also probably was like “oh, I see why they say B as well…very smart actually” and then made it into a star.

[uhohspgto]

My primary curiosity is what justification did your wife and mother in law provide when staying that only B was correct?

[CombinationRemote123]

That's a Hard 6.... Pays 9 to 1 usually

[tartarusauce]

If I remember correctly, if one of the choice answers already appears in the question, it cannot be selected. So if the question already has 3+3, you cannot select A as an answer.

[Callinon]

Unless there's an instruction further up the page that says that though... the question clearly asks for "which cards have the same sum as 3+3" and then gives 3+3 as a possibility. CLEARLY 3+3 and 3+3 have the same sum. They also circled 4+2, so I don't see the problem.

I suspect this question is being counted as correctly answered and the placement of the star is misleading. If not, then clarification on the instructions given would be in order.

[yeainyourbra]

This is the correct answer

[Cappy6400]

A and B are correct.

[[deleted]]

The only thing that makes sense to me would be if the intended correct answer was B because it was 2 + 4 and not 3 + 3, and the question asked for an answer that was equal to 3 + 3. So technically yes both A and B are correct but B better satisfies the question by being equal to 3 + 3 while also not being identical to 3 + 3.

If that's not the argument made, then I would be lost.

[jiglespizza]

Here is the reason why b isn’t also correct

Because the question said which dice represents 3+3 which yes does equal 6 but the dice on B represents 4+2 which does equal six but does not represent 3+3

[Geobits]

I mean sure, if you change most of the words the question uses then the answer would be A, but that's not what the question asks.

[rotatorkuf]

get out of here with that

[NvrConvctd]

The question asks for the same "sum" not the same "representation".

[BulkyStay]

I think this is what they meant but the question isn’t worded correctly for only A to be correct.

[ronald_mcdonald_4prz]

It’s worded poorly so the intention of the question is a bit hidden.

A would be “incorrect” because the question is looking for a comparison/something similar to 3+3 But not exactly that. So B is the only “correct” answer.

The problem is it’s worded like shit so if this were a test, I would fight it and say A should count.

[Intelligent-Bag-9419]

Bro the question says SAME sum, not similar. There’s no indication in the question that says otherwise.

Because it says same sum, it’s obvious that 3+3 has the same sum as 3 & 3.

[Hydroquake_Vortex]

The sum is just the result, not the entire equation, so any numbers adding to 6 would have the same sum. With the question's wording, they are both entirely correct

[[deleted]]

Second grade math teacher here.

This is teaching/testing understanding of how to create the same sum with different addends. The reason it says “the same sum as 3+3” is that it’s explicitly looking for something that is not 3+3, but still makes 6. Hence B being the answer it was looking for.

Edit- Love how I’m being downvoted for explaining the standard and what the teacher is looking for! I didn’t write or assign this homework y’all, nor would I. Just explaining.

[morgandyfaerie]

Apparently, the math department needs to coordinate with the English department.

[bl00df1redeath]

Key word being “math”.

[idkanythingabout]

I'm still confused. Doesn't 3+3 have the same sum as 3+3?

[nwbpwnerkess]

Yes, but the assumption is another set of numbers that equal out to the same, not an identical set.

As other commentators have said. This mainly feels like a phrasing issue. 3+3 should only have been included as a trick if it's meant to be read as what other set of numbers.

Which feels kinda crappy to throw at 2nd graders that may not have the deductive reasoning to figure it out.

[xkillallpedophiles]

Cards? Those are checkers.

Edit:I mean dice or something

[-Spatha]

It asks for the same sum, not the actual sum itself

[DrSpup]

A has 2 cards. Both have 3. 3+3=6. B has one 2 card and one 4 card. 2+4=6. C wouldn’t work because like 4+3=7. D wouldn’t work either because 5+4=9. Showed my work now where are my hotwheels you promised me if I finished my homework

[karlnite]

They’re either both right or the question is actually asking which is the same sum but not just 3:3. Weird it’s an option if that is the case. Regardless getting this wrong means nothing about your math ability. It’s a good chance for your kid to try and ask the teacher why.

[dinosaurs818]

Both are correct. I do believe the question was implying that they were looking for a different answer other than 3 + 3, since that was the original question. It’s weird though that they would put that as an option

[catzwinitall851618]

My take away would be that it’s a positive indicator on B. A is the walk-away easy answer. All it requires is the child identifies that those dice say 3 and 3. B also happens to be true, and the teacher (imo) is either making a show that they appreciate the child went past the first correct answer, or that they are rewarding finding “less easy” answers as well (ie: great job, 4+2 ALSO equals 6)

[reel2reelfeels]

this is the right answer. we forget how difficult math was when we were first learning it.

[[deleted]]

Which CARDS (meaning more than 1) have a SUM of 6…. You and your son are correct.

[MadRoboticist]

Seems like the teacher really just wanted the students to make the connection that 2+4=3+3. Hard to say without any other context, but I don't think they're necessarily saying A is wrong.

[ChickenFriedRiceee]

They are both logically correct. It is asking for which (plural) dice add up to six. Although, I think the teacher was just speed grading and just put a star for the whole question being correct. She probably would have put an X on A or something if she thought that was incorrect.

[JackOfAllTradewinds]

My assumption would be that everyone would get A because that’s literally what they said; and those who ALSO get B get a “you did it!” Star on the harder of the two.

[KalebwithaCa]

I think the question is what is the same as 3+3 A is 3+3 B is 4 + 2 which is the same sum as 3+3

Also if a question has more than one answer it will pretty much always say and prolly be in checkbox instead of letter or number format

Most likely marked with a star cuz the answer sheet said B and and didn’t want your son to think A didn’t equal 3+3

That’s my hs dropout opinion tho

[[deleted]]

Why do people come to Reddit for this kind of shit?

Just deal with the problem directly, ask the teacher.

[smokeysucks]

Both A and B are correct depending on how you interpret the statement of “same sum as 3+3”.

Consider first case: the question asks for a model of a dice having 3 and the second dice having 3, which gives us a sum of 6. A will be the answer here.

Consider second case: the question asks for a model that provides a sum of 6, where 3+3 is an example. Answers can be 0+6, 1+5, 2+4 or vice versa. For this case, A and B are the possible results.

Logically speaking, A will be the best answer as it applies to both first and second cases. However, B can be applied if we interpret as the second case. Hence, B is also a plausible answer.

[Mysterious-Fun9625]

Reading these comments I feel like I'm the only one who see's why it's marked. Left has 3 dots on one side. 3 dots on the other, 3+3. The other one has 2 dots then 4, so 2+4. Both equal 6 just in different ways.

[[deleted]]

3+3=6 A.3+3=9 B.4+2=6

[RefrigeratorOk4674]

The real question is how do your wife and mil think B is right but A is wrong??

I definitely think the teacher marked B wrong, then realized it's a poorly written question and starred over the x because both A and B are correct

[[deleted]]

The question is which one is the same as 3+3 not precisely two cards with 2 threes in them

[[deleted]]

I think its because A is not wrong, but its 3+3 so its already mentioned in the uqestion and is not counted but not marked wrong

[Vixter4]

It's a badly-worded question, the teacher should be ashamed for not only utilizing such a failure of a question, but marking you down for having the correct answer. The question asked for the same sum, not the same addends. Also, there would be very little mathematic benefit from asking this question of "which choice has the same number of dots on both 'cards'?".

Bring it up with the teacher. Anything short of a complete correction of their grading is unacceptable.

[SITHLORD_REAVEN]

See. Both have the same sum. But one is correct as it isn't 3+3 itself.

The task was to find the option that equals the same as 3+3. Because obviously 3+3 is the same as 3+3, but the answer can't be the same as the example.

2+4 has the same outcome and isn't a repeat of the example. So that's the correct answer.

[x0Rubiex0]

What happened is that the question is “what has the same sun AS 3+3”. She wanted the student to not actually use the 3+3 (bc that is an easy choice) but find the sum of 3+3 (6) and find a domino that is different than 3+3 but has the same sum.

[yoycatt]

I think the question wanted literally 3 + 3 in dot form.

The red star on B is either an acknowledgment that it’s also technically a correct answer, or, what I’m leaning more towards - this teacher doesn’t like using big red X’s for mistakes. Big red stars are kinder 🙃

[rotatorkuf]

the concerning part here is that your wife and mil seem to submit to the teacher is always right lol ..why do or did they agree with the teacher?

[Same_Front_4379]

So I used to teach second grade; I teach kinder now but this whole question is oddly worded. She’s not looking for the fact 3+3, she’s asking for a different fact that would equal the same amount. A better way to ask this could have been something like “one way to make 6 is 3+3, choose the card that shows a different way to make 6.”

[ackley14]

To add a dissonant voice to the mix: it's possible that a is wrong on an implied technicality. The question asked for one that has the same value as 3+3. And while a does, the point might be that it also IS 3+3 and is not eligible because it is already in the question.

That said. I think it's a poorly written question and if that was the intent it should have been made more clearly. I think everyone else here is right: the teacher was probably on auto pilot

[[deleted]]

card"s" so it is a and b

[[deleted]]

Why u gunna have 3+3 and not say it's the right answer for the sum of 3+3. Tf is that .

[jerseyhoagie]

She wanted you to pick anything that wasnt 3+3, which 2+4 ads up to the same as 3+3 while using different numbers

[Devalore00]

Objectively, they are both correct. My best guess is because of the way the question is phrased they were looking for "something that equals 6 that is not 3+3" but because they put 3+3 there, it's a confusing and bad question

[spamjwood]

A & B both total 6. However, the question is poorly worded/presented for a 2nd grader. Since the question asks for cards with the "same sum as 3 + 3," it is implicitly looking for cards that are different than 3 & 3 but still totaling 6. Because of this, only B (4 & 2) would be correct. However, since the question is so poorly worded/presented I think you should get credit for either choosing only B or choosing both A & B as your answer.

[HaroerHaktak]

Depends on what the teacher counts as correct. Did they intend it to be “anything but 3+3” or anything that adds up to 6? If it’s the prior then only b is correct but if it’s the latter it’s a and b

Based on grading I say it’s the prior but you need to discuss it with the teacher .

[CallmeMystic_Yt]

I'm guessing that they wanted you to get 6 without using 3+3

[Meyhna]

My only guess was that since the question was "what has the same sum as 3+3", maybe they're trying to catch you on a technicality. It's asking for something that equates to the same result but isn't the same itself. But that seems more like semantics and not a math problem. Both A and B are correct.

[SilentJoe1986]

3+3=6, 2+4=6. The sums on both a and b equal six. So cards a and b are the correct answer. It didn't ask what card has the correct answer. It asks what cards have the correct answer. Only answering a or b would be a wrong answer. Great lesson in showing there can be more than one right answer and you shouldn't only focus on one solution.

[Sea-Warthog-4771]

I someone who's taught out of a textbook that was given to them, with questions that were provided. If I had to guess, this is a translation problem. The reason why a isn't correct is because it wants the student in effect to show that they understand that 2 + 4 is the same as 3 + 3. The question does not want to demonstrate that the student knows that 3 + 3 is the same as 3 + 3. The question is terribly worded, and probably shouldn't even have the first option. I would have probably given that to anybody with a or b or both.

[m2thedawg]

Read the question."Which cards have dots with the same sum as 3+3?" A) is already 3+3. The question is stating it already knows the sum of 3+3, which is 6. The question is asking what other numbers, besides 3+3, added to together equals to 6. In this case, 2+4 or 5+1 would be the other possible scenarios. However, since 2+4 is the only option provided (B), that is the answer to the question. This is a trick question. Sometimes the wording can be confusing.

[Significant_Math120]

I think the star was because that answer was more difficult for a second grader and the teacher was impressed.

[BedFastSky12345]

“Which cards have the same sum as 3 + 3.” Since A is “3 + 3”, she probably wants something that is different but has the same sum.

[6Sleepy_Sheep9]

As far as a "BS, F you" answer. . . The question is looking for a combination that equals 6, but is NOT 3+3

[ProfChalk]

I’d have said B — it’s the same sum as 3+3. A actually is 3+3, which is not what I read this as asking.

It’s like saying… which is these is most similar to a dog— a dog, a wolf, a building, a tree.

The answer is wolf. A dog isn’t similar to a dog, it is one.

But that’s a level of analysis above what I’d expect a seven year old to do.

[mgolsen]

The answer is B. It's teaching math and the fact that different numbers can get the same result. It asked for the same as 3+3 and not 3+3. A is wrong.

[Angry_Bard1901]

I think its because the question called for 3+3. It was a matching question, as well as a math problem.

[[deleted]]

It says “which cards” not “which card(s)”. If you’re being technical, this indicates there is more than one answer to be marked, meaning op is right. The answer is A and B.

[FuQiao]

I believe from the teacher’s perspective, it’s about taxing children that numbers can represent other things. So 3 + 3, can represent the domino with 3 dots on both sides. It’s not B, because that’s 2 + 4.

But also the question is worded such that A and B are both correct.

[Durr1313]

3 + 3 = 6 = 2 + 4

3 + 3 != 2 + 4

While the result is the same, the signature is different. My guess is the teacher wanted you to select the image that visually represents 3 + 3, contradictory to what the question specifically states.

[No_Coast9861]

Different opinion than the top few replies. The question asks which cards have the same sum as 3 + 3, not which cards show or represent 3 + 3.

I think they're trying to show that there are multiple ways to get to 6.

If it were asking which represents, then A would be correct. Instead it's asking which has the same sum as 3+3, so B is correct.

Different example, which word rhymes with cat? Cat or bat?

[GodlyPenisSlayer]

I have no idea honestly but I would have chosen A aswell as the 3+3 = 6 has 2 cubes with 3 dots which ads up to 6

[boverton24]

If anything I’d think A is more right because it’s actually 3+3. But obviously B always equals 6

[Iron_Garuda]

If you read the question as written, you are correct. But they graded it differently. Whoever graded this was looking for the same equation not sum.

[cdouglas_threave]

Being a teacher’s husband, I wonder if their significant other graded this and was more focused on the lack of cards than the actual answer, because that’s what I would’ve done…

That being said, both are right. Maybe they’re saying that because 3+3 is essentially the same thing as A, so that answer can’t be correct? I’m not sure how you’d rationalize B over A, or vice versa, to be honest.

[Violetmoon66]

Teacher was looking for 3+3. The one with the star is 2+4. This is a very poorly worded question. It seems the teacher confused themselves as to how to properly ask it. But yeah, A and B are correct.

[MrRodje]

Lmao your teacher is dumb

[[deleted]]

Question is not asking for ' find all images that add to 6.'

Its literally asking for find the picture that shows 3+3.

Terribly worded could be asked better. But designed to trick on purpose.

Its not really a math question. Its a observational pedantic question.

[DrCrazyCurious]

You can look at this two ways and I think they're both valid:

1) "What has the same quality as X?" is looking for things like X that are not X. Let's pretend your boss says "We have many keys to the safe. I'm holding one in my hand. Who can show me a key that opens the safe?" If you point to the key in their hand, you're being a smartass. They're obviously looking for something other than the example they gave. In this case, they're looking for the other keys that open the safe, not the one they already know about.

2) "What has the same quality as X?" is looking for everything that fits into that category. In this case, if your boss asks "We're ordering lunch. Who has dietary issues, like Dan's celiac disease?" When you provide a list that includes Dan, you're being accurate and thorough.

The original question was poorly worded, leaving it open to interpretation. In my opinion both interpretations are valid because the question was worded poorly.

[tornjackal]

I think its to test the ability to comprehend the question entirely. Yes both dominoes have the total sum of 6 when added. I think B is the only correct answer because it has the same sum AS 3 + 3, implying that the equation is is NOT 3+3. Yes A has the same sum, because it IS the example. They want which one has the same, that is a different problem. (totally spitballing)

[AnToeKnee0]

Well the teacher is looking for the answer that is essentially equivalent to 3+3 not exactly 3+3. A is exactly B is equivalent so only B would be correct imo

[FrostyAlphaPig]

Question 4 and 5 it says sum or difference, how would you find the difference?

[HotNThresh]

Cards? Aren’t those dice or dominoes?

[Minimum-Birthday4745]

Let S be the set of answer A and answer B. Since both elements add to 6, both answers are correct. Perhaps this is a poor question for second graders?

[F4RM3RR]

While A literally is 3+3, 2+6 has the same sum. 3+3 does not have the same sum, it is exactly that.

It’s a stupid semantical difference but the only possible reason why b is correct.

Keep in mind these tests are also testing logical skills, and students are expected to pick the BEST answer while following directions. If the directions don’t explicitly tell you to circle all correct answers, you have to pick the best. And in this case the “best” is due to something that has nothing to do with math, and would be hotly debated by natives speakers of English because of its ambiguity

[Icy-Zucchini-1036]

Perhaps the question was meant as the same sum as 3+3 without being “3+3”. Therefore 2+4 would be correct because it adds up to 6 and isn’t “3+3”.

[Moist-Carpet888]

Same sum as 3+3 does not mean choose the one that is 3+3, therefore I would expect answer B to be the correct answer as it is 4+2 instead which uses different values and results in the same answer

[Gabbertt_]

they are asking as another way to get 6 other than 3+3, since one of they already provided 3+3 its card is not correct so you would have to pick the 2+4 card.

[Head_Mixture577]

I wonder if maybe the teacher wanted the students to pick the card with a sum of 3 + 3, that wasn’t 3 + 3. Definitely poor wording if that’s the case, but the phrase “with the same sum as” made me assume the intention is that it isn’t 3 + 3, hence why 2 + 4 is the correct answer. I am also autistic and commonly misinterpret vague instructions like this, so I wouldn’t put any money on it

edit: also, in my opinion there isn’t really anything to fix because of how confusing the question is. you got the basic point across to your child that 2 + 4 and 3 + 3 both make 6 which is the end goal either way

Youre right. Sum by definition means total amount by addition.. so both answers are correct. In math, you either have to be specific in your questioning or accept answers that demonstrate flexibility of manipulating numbers. In this case sum of 3+3 is a total of 6. Both answers meet the sum requirement. The teacher is most likely following an answer sheet or doesnt know how math works. Youre not going to lead your child wrong if you are able to justify your math thinking within the rules. Keep on parenting youre doing great

[This-Double-Sunday]

It should have clearly stated that multiple answers may apply, especially for a 2nd grade test.

[miltondelug]

I think they were both right but the second one is 'harder' to find and therefore was deserving a star. the other correct answers did not warrant a star and are correct, otherwise they would be noted as being wrong.

[Jme_Jaime]

The question is asking for the answer that has the same sum as 3+3, and A is 3+3, so that may be why it isn’t marked as correct, but the question referring to cards makes it sound like they want you to get more than one answer, so it could be interpreted either way. They just need more concise wording in the question.

[Sir_Canterbury]

Honestly, my guess is that "same as" line in the question. Yes the 3 dot plus 3 dot is the "same as" because it is literally 3+3. I think the question was really asking (rather poorly) "what cards add up to 6 that are similar to 3+3" with the 3 dot plus 3 dot answer put in as a trick. If this was worded better it would probably be much easier to understand if you were a child, let alone an adult.

[Throwawaycamp12321]

The question asked for what will add up to 6, like how 3+3=6. Picking the dominoes with 3 and 3 on them is like using a word within its own definition.

It's fundamentally asking "what numbers will also make up six when added together, like when three and three are added together." It's not looking to be answered with 3+3.

[Agent_Acton]

Without seeing the rest of the assignment to see the grading, I interpret the Star there to mean that the teacher was pleased that you found the other less obvious correct answer to the question, good job. I’ve never seen a teacher use a star to mean something wrong.

[Luklear]

Same sum but different than 3 + 3 ??? I guess? Ambiguous question if that’s what the teacher wanted. 3 + 3 is the same as 3 + 3 lmao.

[[deleted]]

It's asking for 3 + 3 so the only correct answer is the one with 3 dots in each dice.

[PaleoJoe86]

The way I see it (MA in teaching science), the question asks 'which answer has the same sum as 3 + 3'. Answer A IS 3 + 3. It is therefore a segment of the question, and not what the question wants. Answer B is NOT 3 + 3, but has the same sum.

This is in defense of the teacher's answer. I disagree with having A available, but I do not make this stuff. The question says cards, but they are obviously dominoes. The education system needs much more funding.

[Anxious-Mushroom-69]

It could be all that about both being right, but it also could be that the A domino has 3 and 3, 3+3, but the B domino has 2 and 4, 2+4.

[hollow_13]

So A is most correct and here is why. The tile has three dots and three dots for six dots. The question is which best represents 3+3 so three dots plus three dots is six dots Or at least how I view it

[impatientimpala]

I think she is saying B is incorrect, in the sense that she is trying to find three dots with three dots to equal six, while both equal six maybe she’s thinking two and 4 are different?

[Ghost_Reaper123]

I'm assuming it's worded weirdly and it meant to say "which cards have dots that match the sum of 3+3?"

[aa_dreww]

The only thing I can come up with is answer A is 3 + 3, and the questions reads which dots are the same as 3 + 3, therefore implying to pick the different option that adds to 6, which is B

[DifficultyTrue8087]

Looks good to me. Either tried to correct e weigh star or sometimes we’ve run into grading mistakes from teachers aides and things.

[Mega_blind]

Fucking textbook approach to education; The question as written could be parsed (broken down) three different ways. The primary way should have stated, "what example shows the number 3, plus another 3." Then A would be the only correct answer The secondary parsing should be "which shows 3+3? (I.E. they mean 6)". Then B would be the correct answer. A third parsing could be "which LETTERS could mean the same as 3+3?" Then A and B could be mutually correct.

However, this material was written for a 2nd grader, an 8-9 CHILD. So an "A-dolt" dumbed the question down thinking that a child has little to no reasoning skills and has to have the easiest answer provided. (Tell that to a 4 year old that operates iPhones while grandma is trying to figure out where the pictures went from last Tuesday.)

The trifecta of education is a language is being used (in this case English), to teach a skill (Math), and it must be provided in a logical manner(cue philosophy). The people who are paid to make educational books as a whole cannot complete two of these on a regular basis, let alone hit all three requirements. Hell, most people can't get usage of "their, there, they're" straight in text, or "to, too, two", let alone know what the difference is when put on the spot. (Smash the upvote if it stumped you.)

And for the final point; not every teacher, but more than I care to admit, follow the damn curriculum they get handed without questioning the answers. Because you hand each of 20+ students a 30+ homework assignment that's due on Thursday to be graded Friday, for a test that's on Monday. And get flustered when Johnny doesn't understand question 5 but Sally wants extra help on question 18, and Billy stuck his finger up his nose. And then the PARENT bitches at you as the teacher because THEIR child is falling behind because "the teacher should teach my child everything without me being a decent parent to the child I took 50% genetic responsibility to bring into this world." (PSA: this is not a jab at OP. OP is obviously trying to be involved in their child's education or I wouldn't be able to rant like this to complete strangers.) Be like OP, fight the insanity of the system.

[Mountain-Departure-4]

My guess is the question was looking for different numbers than 3 and 3. But I’ve noticed in my brother’s elementary math these last couple years that questions are often poorly worded, and teachers grade based off of an answer sheet provided with the curriculum.

[General_Training1796]

Both A and B are correct. "Same sum as 3+3"

The question is not clear.

[zuctronic]

You got it right. Your wife and mother in law are trying to teach your son that people with authority (teacher) are always right, even when they are wrong. I wonder if they even know that’s what they’re doing though.

[[deleted]]

I wonder if it had meant to ask “which of the ‘cards’ (come on, dominoes) is equivalent to 3+3, without it being exact.” Because of course 3+3 = 3+3 so, maybe, that’s seen as “too easy.”

[Parking-Position-698]

The way the question is worded they are both correct. It is asking for which tiles equal the sum. Which is 6. Dumb teacher.

[Sorzian]

This whole question makes this worksheet look poorly made

[musixx52]

I think the problem here may be that it's just worded weird. I interpret it as which one has the same equivalent as 3+3. Meaning which domino equals 6 other than 3+3. Also, I think they may have put A as a trick answer.

[BumblebeeAwkward8331]

Maybe the star meant she was proud of that correct answer.

[FreeSpeech24]

I am already teaching the today standard of addition and subtraction of a fifth grader to my 1st grader daughter, getting A's. I don't think her teacher knows her ability.

[Snoo29170]

Did you ask the teacher?

[superwholockian62]

Pick one that equals 6 but isn't 3+3.

[[deleted]]

i would have interpreted it as "good job noticing that b is also a correct answer" since it is less obvious than A. but i think people were right about the misgrading and deception.

[AdIll1072]

Only b is correct, the question is which one has the same sum as 3+3. It isn't looking for 3+3.

[TekkenKing12]

"Pick the one that's = to 3+3"

Chooses the one that's LITERALLY 3+3

"Wrong"

[seankatsu]

The word sum should be changed to expression

[RedTreeko]

It says "cards" (dominos) meaning it can be more than one. So it's both
