Summer Review Sheets — Answer Key
Part A: Multiple Choice
Circle the best answer for each question.
1. A camp store sold 9 bags of trail mix at 7 dollars each. How much money did the store earn?
A) 56 dollars
B) 16 dollars
C) 63 dollars
D) 72 dollars
9 bags × 7 dollars = 63 dollars. Equal prices per item always call for multiplication.
2. Read: "Mia practiced diving every morning and entered the competition feeling confident." What can you infer about Mia?
A) She had never dived before.
B) She was well prepared for the competition.
C) She was nervous about competing.
D) She did not enjoy diving.
Practicing every morning and feeling confident are clues that Mia prepared hard. The other options do not fit these text clues.
3. 81 campers are divided equally into 9 teams. How many campers are on each team?
A) 8
B) 72
C) 9
D) 10
81 ÷ 9 = 9 campers per team. Check: 9 × 9 = 81, which is a square number.
4. Which fraction is NOT equivalent to 12?
A) 24
B) 36
C) 48
D) 38
38 does not simplify to 12 because 8 ÷ 2 = 4, not 3. The other fractions — 24, 36, and 48 — all simplify to 12.
Part B: Fill in the Blank
Write the correct answer on each line.
1. 8 times 8 water balloons equals 64 water balloons.
8 × 8 = 64. This is a square number because the same number is multiplied by itself.
2. If 510 of the race is done, that simplifies to 12 of the race.
Divide both 5 and 10 by 5 to simplify: 510 becomes 12. Half of ten is five, so five tenths equals half.
3. 42 divided by 6 equals 7.
42 ÷ 6 = 7. Check: 6 × 7 = 42.
4. A character who changes during a story is called a dynamic character.
A dynamic character grows or changes over the course of a story. Think of 'dynamic' as 'moving' — these characters evolve.
5. A swimming pool is 10 feet by 5 feet, so its perimeter is 30 feet.
Perimeter = 10 + 5 + 10 + 5 = 30 feet. The shortcut 2 × (10 + 5) = 2 × 15 = 30 gives the same result.
