Winter Holiday Math & Reading — Answer Key
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
A scarf costs $24.50 and is 50% off, so the sale price is $12.00.
Corrected: A scarf costs $24.50 and is 50% off, so the sale price is $12.25.
The corrected sentence is: "A scarf costs $24.50 and is 50% off, so the sale price is $12.25.". The original sentence "A scarf costs $24.50 and is 50% off, so the sale price is $12.00." contained an error that needed to be fixed.
2. Fix the sentence:
Jake bought 3 gifts at $7.25 each and spent $21.25 total.
Corrected: Jake bought 3 gifts at $7.25 each and spent $21.75 total.
The corrected sentence is: "Jake bought 3 gifts at $7.25 each and spent $21.75 total.". The original sentence "Jake bought 3 gifts at $7.25 each and spent $21.25 total." contained an error that needed to be fixed.
3. Fix the sentence:
A recipe needs 34 cup of sugar and 14 cup of cocoa, so 34 + 14 = 48 cup total.
Corrected: A recipe needs 34 cup of sugar and 14 cup of cocoa, so 34 + 14 = 1 cup total.
The corrected sentence is: "A recipe needs 34 cup of sugar and 14 cup of cocoa, so 34 + 14 = 1 cup total.". The original sentence "A recipe needs 34 cup of sugar and 14 cup of cocoa, so 34 + 14 = 48 cup total." contained an error that needed to be fixed.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. A sweater costs $34.00 and is 25% off. The discount amount is $8.50.
25% of $34 = 0.25 × 34 = $8.50.
2. Hot cocoa mix costs $2.75 per box. Three boxes cost $8.25.
3 × $2.75 = $8.25.
3. A gift bag holds 13 of 24 ornaments. Each bag holds 8 ornaments.
13 × 24 = 8 ornaments.
4. The word for a price reduction at a store is a discount.
A discount is a reduction in the original price of an item.
Part C: Short Answer
Answer each question in one or two complete sentences.
1. Maya has $50.00. She buys a hat for $12.50 and gloves for $8.75. How much money does she have left? Show your reasoning.
Sample answer: Add the two purchases: $12.50 + $8.75 = $21.25. Subtract from $50.00: $50.00 − $21.25 = $28.75. Maya has $28.75 left.
Total spent: $12.50 + $8.75 = $21.25. Change: $50.00 − $21.25 = $28.75.
2. A store sells wrapping paper for $3.50 per roll. Explain how you would find the cost of 4 rolls and the change from $20.00.
Sample answer: Multiply 4 × $3.50 = $14.00. Then subtract from $20.00: $20.00 − $14.00 = $6.00 in change.
Step 1: 4 × $3.50 = $14. Step 2: $20 − $14 = $6 change.
