A work mat to explore regrouping when subtracting.
Use this resource when teaching subtraction with regrouping.
Students use the mat to create two-digit numbers with base 10 blocks and then regroup as necessary.
This mat is perfect for reinforcing the strategy of regrouping when subtracting. It is an ideal resource to use when working on mental math in preparation for learning to write the standard algorithm.
Print and place the mats in a dry erase pocket for students to use repeatedly. Alternatively, provide each student with a black-and-white version to paste into their workbooks.
