Review of Algebraic Thinking and Operations

Kip has 10 action figures. Nicole has 3 times as many figures. If Nicole has f figures, which equation represents this situation?

• 3 x 10 = f

• 10 + 3 = f

• 10 x f = 3

• 3 + f = 10

This week Leslie picked 48 tomatoes from her garden. This is 4 times as many as picked last week. Last week she picked t tomatoes. Which equation represents this situation?

• t = 48 + 4

• t = 4 x 48

• 4 x t = 48

• 48 = 4 + t

Rita made 3 times as many paper flowers as David did. Together they made 20 paper flowers. How many paper flowers did David make?

• 4

• 5

• 15

• 16

Kelsey has 8 sheets of stickers with 12 stickers on each sheet. Ricardo has 10 sheets of stickers with 15 stickers on each sheet. Ricardo buys 4 more sheets of stickers like the ones he has. Which equation could you use to find s, how many more stickers Ricardo has than Kelsey has?

• 10 x 15 + 8 x 12 = s

• 8 x 12 - 10 x 15 = s

• (15 + 4) x 10 + 8 x 12 = s

• (10 + 4) x 15 - 8 x 12 = s

Joachim and Sandra used the rule "Add 4, subtract 2" to make this sequence of numbers. 5, 9, 7, 11, 9, 13, 11, 15, 13, 17 If the pattern continues, which are the next two numbers in this sequence?

• 13, 11

• 13, 15

• 15, 19

• 21, 20

Danny collects stamps and displays them in a stamp book. The book has 6 pages with 12 stamps per page and 9 pages with 10 stamps per page. He sells 15 stamps at a stamp show. Which equation represents s, the number of stamps he has now?

• (6 x 12) + (9 x 10) - 15 = s

• (6 x 12) x (9 x 10) - 15 = s

• (6 + 12) + (9 + 10) - 15 = s

• (6 + 12) x (9 + 10) - 15 = s
