School Supply Run
School Supply Run: An Interactive Decimal Operations Worksheet for Back to School
Give students a real reason to add, subtract, and multiply decimals. In this self-grading digital math activity, each student gets $40 to spend on school supplies before the first day. They price out purchases, build their own cart, and keep it in budget while a live budget bar reacts to every choice they make. It is a hands-on way to review decimal operations at the start of the year.
Built for middle school math, School Supply Run works as a first-week review, a warm-up before a decimals unit, or a spiral-review activity. Because it is fully interactive and auto-graded, you get instant insight into who has mastered decimal computation and who needs another look, with no answer keys to grade by hand.
What students practice:
- Multiplying decimals by whole numbers to find the cost of multiple items
- Adding multiple decimal amounts to reach a running cart total
- Subtracting decimals to calculate remaining budget
- Comparing prices and reasoning about what they can afford
- Working within a real-world constraint using money and percentages
What makes this worksheet different:
- Fully interactive and auto-graded, with immediate feedback on every answer
- A live budget bar that turns from green to red the moment a cart goes over $40
- A build-your-own-cart activity with spinners, so students experiment and see results in real time
- Randomized prices for every student, which discourages copying and makes the activity reusable across classes and years
Standards alignment:
- Primary standard: CCSS 6.NS.B.3 (fluently add, subtract, multiply, and divide multi-digit decimals)
- Bridges grade 5 review: CCSS 5.NBT.B.7 (decimal operations to hundredths)
- Suitable as review across grades 6, 7, and 8
Format and use:
- No printing, no prep, and no manual grading
- Works for whole-class instruction, small groups, independent practice, and remote learning
- Includes a teacher guide with the learning objective, common student mistakes, and a default answer key
Perfect for: back to school, decimal review, real-world math, financial literacy, budgeting practice, digital math centers, and early-year diagnostic activities.
Learning Objective
Students fluently add, subtract, and multiply multi-digit decimals to solve a real-world budgeting problem. Working from a fixed forty-dollar budget, they calculate the cost of multiple items, combine those costs into a running total, and determine how much money remains. They then build their own cart within the budget constraint, reasoning about affordability and comparing prices. This worksheet reviews decimal operations from grade 5 (5.NBT.B.7) as bridge work and anchors them to 6.NS.B.3.
Randomization Available
If randomization is enabled, every student will get different prices for each item, hence the correct answers will be different for each student, this prevents copying of answers.
💡 Tip: When assigning this activity to your classroom, you can optionally enable randomization to give each student a unique version of the problems. When you re-assign the same worksheet, each student will get a new set of questions, helping them master the content through repeated practice.
