We were asked to think about the different types of comparison statements we’ve been writing and our work with rates and unit rates. In this video I’ve addressed 2 questions: 1) HOW have you found these ideas helpful. 2) Make up an example comparing two items using unit rates.
Figures are mathematically similar if they share a scale factor/ratio, and also they have to have congruent corresponding angles. This is true because if there is a triangle, and both have side lengths that are related by a scale factor but don’t have angles that are congruent, the figure is not similar. In order to achieve similarity, both of these reasons have to be true.
True or False…
Any two rectangles are similar:
This is true because all rectangles’ corresponding angles are congruent. If the corresponding angles are congruent, then the shape is similar, which means that the ratio/ scale factor are the same.
Any two equilateral triangles are similar:
This is true because all equilateral triangles’ corresponding angles are congruent. If the corresponding angles are congruent, then the shape is similar, which means that the ratio/ scale factor are the same.
These are bad notes because they aren’t organized and aren’t very clear
These are good notes because the are clear, organized and easy to read
In this assignment we had to draw similar figures to the pre drawn ones on the back page. On the front page we had to find the similar figures and explain why.
I used what we had learned about similar figures to figure out the answers, also I used what learned about scale factors.
A success I’ve had in math was in 5th grade. Ana gave Elijah and I a really hard math problem to work on if we finished our work early. It took us from october-may and we were really happy when we finished it.
A disaster I’ve had in math was in 3rd grade. I had a hard time learning division, but by the end of the year I had it figured out. It also took me a little while to get the hang of stacking, but I figured that out as well.
I like working on hard problems in math. I really like problems that have a trick to it, for example, we did a problem in seminar last year where we had to make a square 5 with with five lines in it or something along the lines of that. We had to convert the square into a 3d square and solve it like that. I also like ken ken and sudoku a lot. I dislike take home tests. Last year I always had a tough time with those, besides the last one.
When I’m studying for math I usually read over all my notes and do some practice problems for it. When I’m doing my math homework I usually listen to music, which makes me more focused. If I get stuck I usually read over the question a few times until I figure it out, and if I don’t get it still, I ask a friend for help.
