on This week in Math, I was mostly reviewing for the Unit Test we had this Thursday. I reviewed big concepts like converting, but what I learned most about in my reviewing, was Pythagorean Theorem. I’ve always known that a2 + b2 = c2, but I wasn’t sure what to do with it. For example, I’d do 32 + 62 = 92, but I wasn’t sure just how to calculate it and get the right answer. So I looked it up, and asked for help from my dad.
Here’s how I worked it out:
a2 + b2 = c2
32 + 62 = 92
9 + 36 = 81
Then, I found out that you must find the square root of the answer.
The square root of 81 is equal to 9. Therefore, c2 = 9.

on This week, we learned about surface area and volume on cubes. I’ve always had difficulty in my previous years, trying to figure out volume. I came to the realization this year, that you multiply the length, width and height together, and you have the volume. It’s so much simpler this year than I remember from previous years, and it makes so much more sense to me. I used to always forget something such as putting it to the cube, for example, 8 inches3. I would simply write 8 inches, and I would get marks off for it. I look forward to learning more about surface area of different shapes, like spheres, for example, is one of the three dimensional shapes I’m interested in learning about.
