Materials(s): Count to 10 Mat, Add/Subtract Mat
Using the Count to 10 Mat and the Add/Subtract Nat, give students addition questions to answer, first by estimating (Count to 10) and then exact (Add/Subtract).
For example, ask, “What is 31 + 68”. First, they round both to the closest 10 and add getting 100. Then ask them to figure out the problem exactly by hopping on the Add/Subtract mat.
