A working mat to explore trading/regrouping when subtracting.
Students use the mat to create two-digit minuends with MAB Blocks and then trade tens for ones as necessary.
This mat is perfect for reinforcing, in a concrete way, the strategy of regrouping when subtracting. It is an ideal resource to use when working on mental computation in preparation for learning to write the vertical algorithm.
Print and laminate the mats for students to use repeatedly. Alternatively, provide each student with a black-and-white version to paste into their workbooks.
