What is another efficient strategy to solve 4 x 6?
Doubling split 6 into 3 and 3 4x 3 = 12 4 x 3 = 12 12 + 12 = 24
subtract a group; 6 x 6 = 36. 36 - 6 = 30
Doubling split 4 into 2 and 2 2 x 6 = 14 2 x 6 = 14 14 + 14 = 28
Add a group; 4 x 4 = 16 16 + 4 = 20

What is an efficient strategy to solve 4 x 6?
Doubling split 4 into 2 and 2 2 x 6 = 14 2 x 6 = 14 14 + 14 = 28
Doubling split 6 into 3 and 3 3x 6 = 18 3 x 6 = 18 18 + 18 = 36
subtract a group; 5 x 6 = 30. 30 - 6 = 24
Add a group; 4 x 4 = 16 16 + 4 = 20

What is a multiplication strategy that you can use to solve this fact: 6 x8
Split the 8 into 4 and 4. Multiply 4 x 8 = 32 4 x 8= 32 32 + 32 = 64
Multiply 6 x 7 and subtract a group. 6 x 7= 42 42- 7 = 35
Split the 6 into 3 and 3. Multiply 3 x 6 = 18 3 x 6 = 18. 18 + 18 = 36
Multiply 5 x 8 and add a group of 8. 5 x 8 = 40 40 + 8 = 48

Use doubling to solve 6 x 9
3 x 9 = 27; 3 x 9= 27. 27 + 27= 54
He subtracted a group.6 x 4= 24 6 x 4 = 24 24 + 24 = 48
6 x 3 = 18; 6 x 3 = 18 18 + 18 =36
3x4 =12 3 x 6= 18 12 + 18= 30
