🎄 Holiday Math Challenge: Can You Bake a Christmas Cake for Less?
With the holiday spirit in full swing, students take on a real-world challenge: Can they bake a delicious Christmas cake for less than the $25 store-bought price? In this festive and engaging 7th-grade math worksheet, students dive into a cost-saving baking adventure that reinforces key math skills through a relatable and meaningful task.
🧁 Worksheet Storyline:
Store-bought Christmas cakes are expensive—each one costing around $25. Determined to spread joy without overspending, students decide to bake their own cake from scratch. They’ll calculate ingredient conversions, find costs using a price chart, and compare the final total to see how much they save by baking it themselves.
📘 What Students Will Do:
- Convert ingredient measurements from cups, teaspoons, and dozens to pounds and standard units
- Use a conversion rule chart and a price chart to calculate the cost of each ingredient
- Add up the total cost of the homemade cake
- Compare their cost to a $25 store-bought cake and calculate savings
- Analyze a pie chart representing the cost breakdown of each ingredient
- Answer questions about which ingredient costs the most and least
✏️ Math Concepts Covered:
- Ratios and unit conversions
- Multiplying and rounding decimals
- Proportional reasoning
- Data interpretation using pie charts
- Basic financial literacy and cost comparison
📈 Standards Alignment:
- 7.RP.A.3 – Solve multi-step real-life and mathematical problems using ratios and percents
- 7.NS.A.3 – Solve real-world problems involving decimals and fractions
- 7.SP.C.8 – Use visual displays of data to interpret and analyze information
🔧 Features:
- Built-in randomization so each student receives a unique problem set
- Fully auto-graded—teachers can sit back and monitor real-time progress
- Includes visual elements like charts and images to support engagement
- Perfect for math centers, holiday-themed lessons, or applied practice
- Brings holiday cheer while reinforcing core 7th grade math skills
