2nd Grade Math 2.8, Different Ways To Show Numbers, Regrouping

We group a number in different ways. When we regroup a number, the total amount does not change. We solve two word problems that involve regrouping place values. This chapter prepares students for adding or subtracting with regrouping (which we will do in Chapter 4).
