Which expression should go in the blank space to make the equation true?

9 x 7 = ___ x 7

A. (4 + 3)

B. (3 + 7)

C. (3 x 2)

D. (3 x 3)

9 x 7 = (3 x 3) x 7
* parentheses mean do that part of the equation
first
9 x 7 = 9 x 7

200

What unknown number makes this equation true?

4 = ___ ÷ 5

4 = 20 ÷ 5
20 ÷ 5 = 4

Which expression is equivalent to 9 x 5?

A. 9 x (5 x 5)

B. (4 + 5) x 9

C. 9 + 5

D. 5 x 9

This is the Commutative Property. You can multiply the factors in any order.

Susan has 3 times as many books as Mary. Mary has 18 books. Which equation can be solved to figure out how many books Susan has?

A. ? - 3 = 18

B. 3 + 18 = ?

C. 18 ÷ ? = 3

D. 3 x 18 = ?

Andrea baked 60 muffins. She made an equal number of each type of muffin: banana nut, chocolate chip, pumpkin, apple crumble, and blueberry. How many of each type of muffin did she make?

12 muffins

60 ÷ 5 = 12

Fill in the missing number to make the statement true.

48 ÷ ? = (12 ÷ 4) + 5

? = 6

(12 ÷ 4) + 5 = 3 + 5 = 8

so . . . 48 ÷ ? = 8

48 ÷ 6 = 8

A. Lucy's grandmother knitted 4 sweaters and 4 scarves.

B. Lucy's grandmother knitted 4 sweaters. She gave Lucy the sweaters and 4 buttons.

C. Lucy's grandmother knitted 4 sweaters. Then, she gave the 4 sweaters to her friends.

D. Lucy's grandmother knitted 4 sweaters. Each sweater has 4 buttons.

Select the list of numbers that are all multiples of 9.

A. 9, 27, 35, 63

B. 9, 48, 81, 90

C. 18, 36, 45, 64

D. 18, 54, 72, 99

A mutliple is a land on number.
If you count by 9, you'll land on 18, 54, 72, and 99.

* these are not all the multiples of 9, just some multiples of 9

Jennifer has a huge flower garden. She grows roses, sunflowers and tulips. She cut flowers from her garden to give to her friends. She put 7 of each kind of flower into 8 vases. How many flowers did she cut from her garden?

168 flowers

Step 1: How many flowers in 1 vase? 7 x 3 = 21

Step 2: How many flowers in 8 vases? 21 x 8 = 168

Jessica solves 8 x 16. She says, " I can find the product if I multiply 8 x 15 and then add 8."

Select the statement that best explains if Jessica's strategy is correct.

A. Jessica is correct, becuase she can change the 16 to use an easier number to multiply, like 15.

B. Jessica is incorrect, becuase 8 x 16 is the same as 4 groups of 8, plus 4 grous of 8.

C. Jessica is correct, because 8 x 16 is the same as 15 groups of 8, plus 1 group of 8.

D. Jessica is incorrect, because she should add 16 instead of 8.

C. Jessica is correct, because 8 x 16 is the same as
15 groups of 8, plus 1 group of 8.

8 x 16 = 128

(8 x 15) + 8 = 128

Using what you know about the Distributive Property and multiplication, find the unknown number to make the equation true.

348 ÷ 6 = ( ? ÷ 6) + (48 ÷ 6)

? = 300

348 ÷ 6 = 58
(300 ÷ 6) + (48 ÷ 6) = 58

Casey mutliples two numbers.

* The first number is 178.
* The second number is a whole number that is greater than 0 but less than 10.
* The product of the two numbers has a 2 in the ones place.

Part A: What is a possible number that Casey multiples 178 by?

Part B: What is the product of Casey's two numbers?

Part A: 4 or 9

178 x 4 = 712 (2 is in the one's place)
178 x 9 = 1,602 (2 in the one's place)

Part B: 712 or 1,602
