Break apart 7 to show 7 x 6
7= 5+2
(5x6)+ (2x6)
30 + 12 = 42
60= 6 x10
(6x4)x10
24x10= 240
90 x 4 =
What is 360
Write all four fact families using the numbers 8, 7, and 56
8x7= 56
7x8= 56
56/8= 7
56/7= 8
12 x 8 =
What is 96
Use two ways to show 45 / 5 = 9 using equal groups. Explain how the 5 means something different in each model.
5 groups of 9
9 groups of 5
Explain: because the factors can flip flop, the 5 could be the number of groups, or the number in each group.
57 divided by 7
What is 8 with 1 remainder?
Write an expression to find the product of 7, 5 and 2. Which factors would you start with? Explain why you picked those factors to do first.
(7x5) x 2 ---Because I can save the 2 for last. Easy to add
(5x2) x7 ---- Because 5x2 makes 10, and multiplying by 10 is easier
(7x2) x 5 ---Saving the 5 for last because I can count by fives easily.
