Unit 2: Whole Number Addition and Subtraction Summary
This unit offers students a chance to review addition and subtraction and extend their proficiency to include sums and minuends to 10,000.

In grade 3 these problems are no longer in separate lessons but one lesson includes combine and change and the next lesson includes compare and equalize. Students do these story problems with sums and minuends to 10,000.
