Module 1: Lesson 21

Which equation matches the cubes to show 4 groups of 2x5?

• 4 x 10

• 2 x 5 + 2 x 5

• 4 x (2 x 5)

• 2 x 5

This shows 3 rows of 4. How do we say that as multiplication?

• 12

• 3 x 4

• 4 + 3

• 12 ÷ 4

We say 3 groups of 4 as 3 x 4. So if we have 3 groups of 2 x 6, we would say that as...

• 6 x 2

• 5 x 6

• 3 x (2 x 6)
