Summer Review Sheets — Answer Key
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
A pool shop sold 7 goggles at $11 each. The total was $78 because 7 x 11 = 78.
Corrected: A pool shop sold 7 goggles at $11 each. The total was $77 because 7 x 11 = 77.
Multiplying 7 by 11 gives 77, not 78, so the total earned from 7 goggles at $11 each is $77.
2. Fix the sentence:
Kira split 84 stickers equally among 7 friends. Each friend got 11 stickers because 84 / 7 = 11.
Corrected: Kira split 84 stickers equally among 7 friends. Each friend got 12 stickers because 84 / 7 = 12.
Splitting 84 stickers into 7 equal groups gives 12 per friend because 7 x 12 = 84, so each friend gets 12 stickers.
3. Fix the sentence:
A beach cooler holds 0.6 kg of fruit and 0.25 kg of cheese. It holds 0.31 kg of food altogether.
Corrected: A beach cooler holds 0.6 kg of fruit and 0.25 kg of cheese. It holds 0.85 kg of food altogether.
Adding the decimals by lining up the place values gives 0.60 + 0.25 = 0.85, so the cooler holds 0.85 kg of food in all.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. A camp orders 6 boxes of sunscreen with 12 bottles each. That is 72 bottles total.
Six boxes with 12 bottles each is a multiplication situation: 6 x 12 = 72 bottles total.
2. A lifeguard shares 96 arm floats equally among 8 pools. Each pool gets 12 floats.
Sharing 96 floats equally among 8 pools means dividing: 96 / 8 = 12, so each pool gets 12 floats.
3. A rectangular splash pad is 9 feet long and 5 feet wide. Its area is 45 square feet.
Area of a rectangle is length times width, and 9 x 5 = 45, giving 45 square feet for the splash pad.
4. Five kayaks cost $40 each. The total cost is $200 .
Five kayaks at $40 each costs 5 x 40 = 200, so the total is $200.
Part C: Short Answer
Answer each question in one or two complete sentences.
1. A summer camp bought 8 bags of marshmallows with 15 marshmallows each. They used 47 at the campfire. How many are left? Show your steps.
Sample answer: Step 1: 8 x 15 = 120 marshmallows total. Step 2: 120 - 47 = 73 marshmallows left.
First find the total marshmallows by multiplying: 8 bags x 15 marshmallows = 120. Then subtract the 47 used at the campfire: 120 - 47 = 73 marshmallows left. Multi-step word problems like this need you to handle the grouping first, then the change.
2. A story says "Fireflies blinked on and off as the crickets sang their evening song." What time of day is it? How do you know?
Sample answer: It is nighttime. Fireflies come out after dark and crickets sing loudly in the evening, so the clues show it is night.
Fireflies only glow once it gets dark, and crickets are loudest in the late evening, so both clues point to nighttime. Authors often signal the time of day through sensory details rather than stating it directly, and your job is to gather those clues into one inference.
