Halloween Candy Budget Challenge for 4th Grade Math
A student-friendly team project of about 6 to 8 pages that asks 4th graders to plan candy bags for 180 students within a $250 budget. Students practice multiplication with area models and partial products, division-style bag counting, place value, and subtraction and addition to check their totals, then explain their reasoning in writing. It is designed for a multi-day small-group project or a long math block.
Teacher Guide & Tips
- Introduce the mission as a real-world budgeting problem, then have teams read the menu together and discuss what "at least 180 pieces" means before they start calculating.
- Discussion question: Why can't a team buy part of a bag, and how does that change the total cost compared to dividing exactly?
- Scaffold for struggling readers: Pre-compute the total number of students (9 × 20 = 180) with them, and provide a partially completed area model for the first candy so they can see the pattern before doing the rest independently.
- Extension for advanced students: Ask them to find the cheapest combination of five candies that stays under budget while leaving the most extra pieces, and justify the choice with a multiplication model.
- Plan about 3 to 4 class periods of 45 minutes each, with the final Part 6 written explanations completed individually or as a team reflection.
