Each group verbally explains how they solved the problem. As each group explains their answer, write their method on the board or overhead. Some examples of what you may write are: 32 groups of 28 = 896 28 groups of 32 = 896 Extensions: You are likely to get many different answers. Discuss why. You may want to have students use a calculator to check their answers. MA.A.3.2.3 is also covered with this activity.
