Strategies
What strategy goes with this equation: 9 + 9 + 9 = 27
Repeated Addition
what is a fact family?
ex. A fact family is a group of math facts that are related because they use the same numbers.
4 x 2 = ?
8
15 ÷ 3 = ?
3 x 10 = ?
30
what strategy is this: 45 ÷ 9 = 5 NOT THE SAME AS 9 ÷ 45
Communative Property/Order Property of Multiplication
what are the rest of these equations: 3 x 6 = 18
6 x 3 = 18 & 18 ÷ 3 = 6 & 18 ÷ 6 = 3
4 x 12 = ?
48
40 ÷ 4 = ?
10
36 ÷ 6 = ?
6
What is the main name of both of these strategies: Communative Property/Order Property of Multiplication & Distributive Property or the Break It Apart strategy
Properties of Operation
what are the equations to this fact family: 4, 9, 36
4 x 9 = 36 & 9 x 4 = 36 & 36 ÷ 4 = 9 & 36 ÷ 9 = 4
7 x 7 = ?
49
42 ÷ 6 = ?
7
11 x 7 = ?
77
Create an example for this strategy: Using the Relationship Between Operations
ex. 8 x 5 = 40 → 40 ÷ 8 = 5
create a fact family with this factor: 9 with equations
ex. factors: 9, 12, 108 equations: 9 x 12 = 108 & 12 x 9 = 108 & 108 ÷ 12 = 9 & 108 ÷ 9 = 12
8 x 9 = ?
72
108 ÷ 9 = ?
12
72 ÷ 9 = ?
8
Create an example for this strategy: Distributive Property or the Break It Apart strategy
ex. 8 x 7 = (8 x 5) + (8 x 2) = 40 + 16 = 56
create a fact family with the product/quotient: 72 with equations
Factors: 6, 12, 72 Problems: 6 x 12 = 72 & 12 x 6 = 72 & 72 ÷ 12 = 6 & 72 ÷ 6 = 12
11 x 12 = ?
132
121 ÷ 11 = ?
11
84 ÷ 12 = ?
