This week in period 2 math class, I learned something I’m not really familiar with. I learned about algebra tiles and how to make an equation with them.
In this image orange is positive and blue is negative, but for my class red is negative and blue is positive. But when there is no colour colored in is positive and white is negative.
some ways to use this would be solving an equation…
2x x 3
to answer you would put 2 positive rectangles to equal to 2x, then you would put 3 small squares to equal 3.
For me, these algebra tiles help me understand the question better than just looking at numbers and variables.
another way to use these algebra tiles is by…
so the question was
(2x + 1) (x + 3)
with this you write in a multiplication table, you put one half on top then one on the left side. Next you make a square of the whole thing. Then you use each space between variables to create new numbers. Then you calculate what is in the middle. For this question it would be:
This is what I learned this week and I’m finding it fairly easy and fun!
