15 x 6 = 90 ÷ 6 =Take a few minutes and solve these problems.

• Would anyone like to share strategies for how they solved each one? • What do you notice about the numbers in these two problems? • How could you represent these problems with cubes of grid paper? • Using connecting cubes or grid paper, work as a class to construct a representation

for 15 x 16. • Where is the 15 in this representation? • What does 15 mean? Where is the 6? • What does 6 mean? • Where do you see the product of 15 x 16? • Can our cube representation also show 90 ÷ 6? • How?
