How can you use 7 X 10 = 70 to answer 7 X8

• 70 - 7 X 2 = 56

• 70 - 7 = 63

• 56 + 14 = 70

• 70 - 7 X 8 = 14

How can you use 4 X 10 to find the answer for 7 X 10

• 40 + 3X10 = 70

• 40 - 7 X 10 = 30

• 30 X 10 = 4 X 10

• 7 X 10 - 10 = 60

How can you use 8 X 10 to answer 9 X 10

• 5 X 10 + 6 X 10 = 90

• 8 X 10 + 8 X 10 = 90

• 80 - 1 X 10 = 90

• 80 + 1 X 10 = 90

2 X 8 = 16 so 4 X 8 =

• 16 + 2 X 8

• 32 + 2 x 8

• 2 X 8 + 4 X 8

• 10 X 8 - 5 X 8

3 X 9 = 27 so 6 X 9 =

• 27 + 2 X 9

• 27 + 4 X 9

• 27 + 3 X 9

• 27 + 27

How can you skip count to calculate 8 X 5

• 5, 10, 15, 20, 25, 30, 35, 40

• 10, 20, 30, 40

• 40, 80

• 2, 4, 6, 8, 10, 12
