End of Module 3 Review

Write the multiples of 6 up to 10.

Look at the array. What two multiplication sentences represent the array?

• 6 X 2 = 12

  4 X 6 = 24

• 2 X 12 = 24

  6 X 6 = 36

• 2 X 6 = 12

  6 X 2 = 12

• 6 X 12 = 72

  12 X 2 = 24

Tell what the unknown equals.

36 = 9 X r

r = ​ (a)   ​ ​

• 4
• 2
• 6
• 5

Answer explanation

To find the unknown, draw rows of 9 until you get to 36. Then, count how many rows you have.

Solve the equation.

9 + (7x3) = t

• T = 30

• T = 24

• T = 42

• T = 18

Which of the following questions is true?

Hint: Use your magic wand to solve the parenthesis first!

• 6 + (3 x 2) = 18

• (6 + 3) x 2 = 18

• 6 + (3 x 2) = 14

Answer explanation

In the equation, you need to solve what is inside of the parenthesis first.

(6 + 3) X 2 = 18

9 X 2 = 18

18 = 18

What number makes this equation true? 

8 x 3 = (4 x ​​ (a)   ) + (4 x ​ (b)   )​

The carnival is in town for 56 days.  There are 7 days in a week.  How many weeks is the carnival in town? 

Draw a picture and write an equation to show your answer.

There are 72 liters of water to fill the school’s new fish tanks.  Each tank holds 8 liters.  How many fish tanks are we able to fill with this water?  Use a letter for the unknown number to write a division and multiplication equation to represent the problem.  

72 / 8 = ​ (a)  

​ (b)   X 8 = ​ (c)  

T = ​ (d)  

• T
• 72
• 9

What expression would go in the blank box?

• 10 x 8

• 7 x 8

• 4 x 8

• 5 x 8
