Module 3: Lesson 22

There are 8 rows of 10 carpet squares in every classroom. What equation will help me find out how many carpet squares are in ONE classroom?

• 8 x 10 = c

• 10 ÷ 8 = c

• 10 + 8 = c

• c x 8 = 10

Our final answer is 80 carpet squares in 4 classrooms.

• True

• False

4 x 80 =

• 32

• 320

• 160

• 40

If 3 x $40 = m then m =

• $120

• $150

• $140

• $12

What equation can you use to find out how much more money James needs to save for the art kit?

• 200-40 = n

• 200 - (3 x 40) = n

• 200 + (3 x 40) = n

• 40 + 200 = n

How much money does James need to save?

• $80

• $120

• $200

• $100
