Part 1

Let’s explore how multiplication facts build on each other. For example, if 2 groups of 10 equals 20, 3 groups of 10 equals 30. Let’s go!

• If 1 group of 5 equals… (5), then we know 2 groups of 5 equals… (10)
• If 5 groups of 3 equals… (15), then we know 5 groups of 4 equals… (20)
• If 4 groups of 3 equals… (12), then we know 5 groups of 3 equals…(15)
• If 3 groups of 2 equals… (6), then we know 4 groups of 2 equals… (8)
• If 3 groups of 2 equals… (6), then we know 3 groups of 3 equals… (9)
