## Changing the Way Students Think About Math

Math Mights are a way to tie math strategies to characters that will help students understand math processes differently than just solving problems one way. This series promotes students’ communicated reasoning so they are able to confidently explain their thinking. It also provides a common language in schools so students can learn about the characters and the strategies in kindergarten and apply the same strategies to higher level concepts as they grow.

## Special Thanks for Math Mights
