Multiplication
WALT recall the family of facts for multiplication and division
I have learned how to reverse problems. I can turn multiplication around into division and I can turn division around to multiplication.
Knowing multiplication facts will help you solve division problems - this is because they are opposites.
- 8 x 10 =80 3. 12 x 11 = 132 5. 14 x 5 = 70
10 x 8 = 80 11 x 12 = 132 5 x 14 = 70
80 ÷ 8 = 10 132 ÷ 11 = 12 70 ÷ 5 = 14
80 ÷ 10 = 8 132 ÷ 12 = 11 70 ÷ 14 = 5
2. 4 x 15 = 60 4. 12 x 10 = 120 6. 12 x 6 = 72
15 x 4 = 60 10 x 12 = 120 6 x 12 = 72
60 ÷ 4 = 15 120 ÷ 10 = 12 72 ÷ 6 = 12
60 ÷15 = 4 120 ÷ 12 = 10 72 ÷ 12 = 6
120 ÷ 12 = 10 Division
WALT use reversibility of multiplication facts to solve division problems.
42 ÷ 7 = 6 32 ÷ 8 =
How can you use reversibility How can you use reversibility to find the answer? find the answer?
7 x 6 = 42 8 x 4 = 32
So 42 ÷ 7 = 6 So 32 ÷ 8 = 4
