Spring Math & Reading — Answer Key
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
It rained for 9 days in April. Each day got 4 inches of rain. The total rainfall was 34 inches because 9 × 4 = 34.
Corrected: It rained for 9 days in April. Each day got 4 inches of rain. The total rainfall was 36 inches because 9 × 4 = 36.
9 × 4 = 36, not 34. You can skip-count by 4 nine times, or use (10 × 4) - 4 = 40 - 4 = 36.
2. Fix the sentence:
A rain barrel collected 72 gallons over 6 storms. That is 13 gallons per storm because 72 ÷ 6 = 13.
Corrected: A rain barrel collected 72 gallons over 6 storms. That is 12 gallons per storm because 72 ÷ 6 = 12.
72 ÷ 6 = 12, not 13. Check: 6 × 12 = 72, while 6 × 13 = 78.
3. Fix the sentence:
The class planted 26 of a field on Monday and 36 on Tuesday. They planted 512 of the field in all.
Corrected: The class planted 26 of a field on Monday and 36 on Tuesday. They planted 56 of the field in all.
Add like fractions by adding only the numerators: 26 + 36 = 56. The denominator of 6 stays because the pieces are still sixths.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. A pond collects 11 gallons of rainwater each hour for 7 hours. It collects 77 gallons total.
7 × 11 = 77. The 11 times table is easy: just write the digit twice for single digits, or think (7 × 10) + 7.
2. A class shares 117 worms equally among 9 teams for a science project. Each team gets 13 worms.
117 ÷ 9 = 13. Check: 9 × 13 = 117, from (9 × 10) + (9 × 3) = 90 + 27.
3. A rectangular puddle is 5 ft long and 3 ft wide. Its perimeter is 16 feet.
Perimeter = 2 × (length + width) = 2 × (5 + 3) = 2 × 8 = 16 feet. You can also add all four sides: 5 + 5 + 3 + 3 = 16.
4. A jar holds 32 tadpoles and 14 of them become frogs. That is 8 frogs.
To find 14 of 32, divide by 4: 32 ÷ 4 = 8 frogs.
Part C: Short Answer
Answer each question in one or two complete sentences.
1. A rain gauge measured 8 inches on Monday, 5 inches on Tuesday, and 12 inches on Wednesday. What is the total? What is the average per day? Show your steps.
Sample answer: Step 1: Total rainfall is 8 + 5 + 12 = 25 inches. Step 2: Average is 25 ÷ 3 which is about 8 inches per day with 1 inch remaining.
Find the total with addition first, then divide by the number of days to find the average. Averages share the total equally across the days.
2. The passage says "Puddles dotted the playground, and children splashed in their bright rain boots." What can you infer about the weather? Explain.
Sample answer: I can infer it recently rained. The puddles and rain boots are clues that it had been a rainy day, and now the children are playing outside.
Puddles and rain boots are visible clues left behind by rain. Good readers use these details to infer recent weather even without being told directly.
