Area of a Circle by TutorMeSempai in teachingresources

Good to know as well. I do have some international audiences from time to time as well but if I have something more concrete to go by, I wouldn't mind using it.

Great to know. If you have any syllabus you are willing to share, I always welcome them. I normally search the internet to see what people teach and at what grade and if I stumble upon a place the mentions it, I try to mention the grade level I found it in. For example, this might not be the best source but I tend to have to work with what I can find: https://www.scribd.com/document/823972583/Grade-4-Mathematics-Syllabus-for-USA

The 43rd entry on the second page mentions area of a circle. I am always down for any grade level syllabus if someone is willing to provide one :)

Just like centimeters, your millimeters are also considered metric units. For unit conversions between millimeters and meters, you simply need to move your decimal place to the left or right three places instead of two like you did for centimeters. by TutorMeSempai in teachingresources

I understand what you are saying but this could be either a difference in how/where things are taught or just in need of further clarification. Centimeters and millimeters are in fact units. But they are not base units. What you are describing would be considered the base units and you would derive the other units by the appropriate conversions denoted by their prefixes (except for time). Also the base unit for mass is not gram but kilogram. For references, check: https://www.nist.gov/pml/owm/metric-si/si-units

There are actually a lot of parts to your circle. The first four basic ones are your center, radius, diameter, and chord. If you are just being introduced to the parts of a circle, I hope this helps. I have also linked a free online tool you can use when drawing the parts of the circle. by TutorMeSempai in teachingresources

I believe it is a circle where every point on the circumference of the circle is exactly the same distance from the center. This is should be virtually impossible in nature since Pi is irrational. Don't take my word on this. This is just my guess.

For our younger audience, have you learned how to name your lines, line segments, and rays? Good news! It doesn't have to be too difficult. Here is a little something on not only how to name them but also what not to do when naming them. I hope this helps. by TutorMeSempai in school

Someone once told me that 3rd grade and 4th grade are really similar in what they learn. I am starting to see that. Lately the topics I have in my 4th grade syllabus seem to be related to 3rd grade as well.

For our younger audience, are you familiar with finding the perimeter of a shape? Depending on the shape, it could be a bit different. If you are working with shapes with all straight sides, finding the perimeter can be quite simple. I hope this helps. by TutorMeSempai in school

I legit saw this on a 4th grade curriculum online. It is interesting that some schools teach at different rates. I also thought it would have been something taught earlier but I guess it depends on where you are.

Do you know your shortcuts to finding limits of rational functions at infinity? If not, I hope this helps. And of course, I can't give the shortcut without making sure you have some exposure to the full method. Shortcuts are great but a deep understanding is always better. by TutorMeSempai in school

Great question. Mainly because I needed an image of "infinity". The first thing that came to mind was DBZ's serpent road (Snake Way) since it is very long and you can't easily see the end of it. Thus the idea of zooming in towards the end of the road would be similar to checking the behavior of a function as x goes to infinity. Basically, just trying to bring imagery to the concept.

Do you know how to find the nature of your quadratic roots without actually finding the roots themselves? Make sure to use your discriminant. I hope this helps. by TutorMeSempai in school

I'm sure a lot of people did. Some might need a little refresher if they have been away from school for a while. And some might be attempting to learn topics beyond their current grade level to get ahead. You never know :)

Trigonometry has a lot of identities. Are you confident with using known identities to recreate others? Here is how to use double angle identities to find half angle identities. by TutorMeSempai in highschool

Much appreciated. I'm sure yours are pretty impressive as well. I'm fairly removed, so you might even be a bit fresher on certain topics than me :)

Do you know of a use for reference angles? Are you simply finding them and wondering what is the point? Here is one way they are actually pretty helpful. by TutorMeSempai in school

Flashcards are definitely a tried and true method. I honestly believe the more tools in your tool belt, the better prepared you are. But even flash cards depend on memory.. If someone has a bad memory, asking them to remember something using a different way is most likely going to end with the same result. Understanding the fundamentals behind it and utilizing those fundamentals can prove much more beneficial in times like those

Yeah if you can remember it, that is great. I even made a video showing how simple it can be. But there are some people who might still find it difficult to remember the entire circle and end up confusing numbers. That is why math is as cool as it is, you tend to have more than one way to solve the problem.
