Amazing Bar Modeling

In 3rd grade you learn how to do bar modeling. When you do bar modeling you might have to do adding or subtracting, that’s because it doesn’t always come right to your head. When you draw bar models you are going to use a lot of lines. Bar models kind of look like bars.  I know it sounds weird,  but it does not look weird. I like bar modeling. I think bar modeling is fun because instead of just doing adding or subtracting you can make it a little more complicated. I also like bar modeling more than mental math because instead of just using lines you can use lines and adding or subtracting. I like adding and subtracting so much because I think it’s fun. I think it is fun because you use a lot of numbers.
