Adding on the Mat

First graders practice modeling 38+46 with blocks. They place the large 10's blocks and the smaller "ones" blocks to illustrate the problem. They count the number of 10's blocks and record the answer. They count the number of ones blocks and record the number-after exchanging 10 ones for a tens block.
