Students correct three holiday shopping math errors — a rounding error in a 50% discount, a multiplication total, and fraction addition with like denominators. Part B has four questions about percent discounts, decimal multiplication, and fractions of a set. Part C has two word problems about remaining money and wrapping paper cost with change.
Correcting holiday shopping math errors — especially the like-denominator addition error and the exact-percent calculation — ensures students apply rigorous computation to festive seasonal contexts.

Winter Holiday Math & Reading
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.
Rewrite: A scarf costs $24.50 and is 50% off, so the sale price is $12.25.
2. Fix the sentence:
Jake bought 3 gifts at $7.25 each and spent $21.25 total.
Rewrite: Jake bought 3 gifts at $7.25 each and spent $21.75 total.
3. Fix the sentence:
A recipe needs 34 cup of sugar and 14 cup of cocoa, so 34 + 14 = 48 cup total.
Rewrite: A recipe needs 34 cup of sugar and 14 cup of cocoa, so 34 + 14 = 1 cup total.
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.
2. Hot cocoa mix costs $2.75 per box. Three boxes cost $8.25.
3. A gift bag holds 13 of 24 ornaments. Each bag holds 8 ornaments.
4. The word for a price reduction at a store is a discount.
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.
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.
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.
Multiply 4 × $3.50 = $14.00. Then subtract from $20.00: $20.00 − $14.00 = $6.00 in change.
