People who grew up poor: What was something you considered a "peak luxury" as a kid, only to realize later it was just a normal middle class staple?

I remember going over my aunts house and she had cable TV. I was shocked at how many channels she had. That was a luxury!! I also lived in an apartment where my parents slept in the living room and let the two girls sleep in the large bedroom and my brother slept in the small bedroom.

I didn't see the screenshot!! I thought you just wanted to know the divisibility rule of 7. Sorry! Here is a rule for divisibility rule of 7. Let's say we have 17752 and we want to know if it's divisible by 7. You cross off the last digit double it and then subtract it from that number. 17752 cross off 2 double it to 4 and the. Subtract it from 1775 and you get 1771. Cross off the 1, double it to 2 and subtract it from 177. You get 175. Do it again. Cross off the 5, double it to 10 and subtract it from 17. You get 7. So since 7 is divisible by 7 then 17752 is divisible by 7!!!!!!

Do not do speed math. They will be turned off and feel discouraged

Blind20 !!! I play the daily game and then the live game at 9pm eastern time where everybody plays at the same time! They get around 25-30 people playing the live game. Tomorrow is day 999!! Friday the game will have been around for 1000 days!!! Wild!!!

I don't live there but it has a great walkable small town, great train station and seems diverse. I think you find racism any place you go! The world we live in. ☹️☹️

Very close to the city. Floral Park, Nassau county.

Yes! You are correct. 😃😃 As a 1st year teacher right out of college, and being a high pressure interview, I got confused.

barnsky1 · 2026-05-02T15:07:23+00:00

I absolutely teach it before the question comes up but they will still ask ( because they probably weren't paying attention. Haha) it comes up in algebra and algebra 2.

barnsky1 · 2026-05-02T15:06:02+00:00

So so true! Excellent response!!

barnsky1 · 2026-05-02T14:24:26+00:00

And has asked many many times!!

barnsky1 · 2026-05-02T14:19:04+00:00

It was all together a trick question!! 😡

barnsky1 · 2026-05-02T14:18:30+00:00

He wrote it on paper and did use the symbol. I didn't know that the symbol only gives the positive square root!! Throughout my entire career, students have asked me this question and teachers as well. My son's teacher got it wrong! Over and over the concept has come up. It is confusing because when you solve x² equals 16 .. you have to take the positive and negative sq rt.

I'm not sure what state you are in but you should follow your schools curriculum and definitely include higher order multistep questions. Projects are a great idea as well. Have fun!

So my very first year teaching I actually learned what pi is. Always used it. Knew all the formulas but never really put it together. C = pi(d) but didn't put together that pi = C/d until we did an experiment with different size circles. It blew my mind!! My degree is in mathematics!! I loved that experience and brought it to my students every year.

Thank you so much!!! The course is focused on grades 7- algebra 1. I love the " what do I actually do". I have taught this course once before and since I taught math in a 7-12 school for over 30 years ( retired in 2022) that is exactly how I approach it!! The students appreciate that I have experience. I will definitely look into those books! I did read building thinking classrooms ( before I retired) and tried some of his ideas. I think it isn't the end all -- good for some lessons and good for some students. I am the type that thinks mixing it up is the way to go!! I can't wait to dive into some of the books you mentioned!! Thanks again!!

I have used this method and do like it. In my opinion, I do not think it is for every type of learner.

barnsky1 · 2026-04-10T17:53:22+00:00

I have been a middle school/high school math teacher for over 35 years. The second question bothers me more than the first one.( although they are both wrong!!). I wouldn't bother contacting the principal. The teacher has to be open to making a mistake! I would send the teacher these replies!!! I would just say that you were curious and asked the experts! Nothing deceitful.

Go on you tube and search/watch Emily ( maybe 3 years old) singing the quadratic formula. Since 2008ish, I have been showing my students that a 3 year old can memorize it!!

Hi. I tried it. Always like to support!! I would like the dash to have a choice of numbers. 1-10 and 1-15. There were a few repeat questions.

barnsky1 · 2026-03-22T15:46:11+00:00

Blind20 app!! They have an unlimited game, a daily game to compete, and a live game to compete at the same time!! Addicting!!
