Dr. Richard Lesh has done extensive research on how to best develop mathematical understanding. These Lesh mats use his findings to encourage deep conceptual mastery of the Common Core math standards.
By solving problems using multiple strategies, your students will cultivate a rich mathematical foundation!
Each Lesh mat asks the student to show their thinking using words, pictures (pictorial or representational), numbers, and in a real-world situation. There are 2 mats for each standard.
All 3rd grade CCSS standards are included (except for OA.7, which is fact fluency).
