In this engaging simulation, students use multiplication and division of rational numbers to track and compare two stock investments over five days—calculating share quantities, portfolio values, and final profits.
Simulate Real-World Investing Using Rational Number Operations!
In this interactive 7th-grade math activity, students step into the role of young investors. With a budget of approximately $2,000 each, they choose between two fictional companies—TechNova Corp. and GreenMart Inc.—and simulate buying shares based on real-world logic.
Students use division of rational numbers to calculate how many shares they can purchase and multiplication to determine how their investment changes as stock prices fluctuate each day. The activity culminates with profit calculations and a comparison of portfolio performance using real-life decision-making.
This is more than just a math problem—it's an immersive experience where students apply rational number operations to analyze gains, compare investment outcomes, and understand the financial world around them.
Students will multiply and divide rational numbers to simulate real-world investment scenarios, including calculating the number of shares purchased, tracking daily portfolio value, and comparing profits and percentage changes over time.
If randomization is enabled, each student will receive:
As a result, answers will vary for each student, making this activity ideal for individualized practice and preventing copying.
💡 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.
Apply and extend previous understandings of multiplication and division and of fractions to multiply and divide rational numbers.

More interactive, auto-graded activities on the same standards and topics.
Students run a ride-share business, calculating profits using multiplication and division of rational numbers. They analyze real-world costs, earnings, and forecast long-term success using math.
A fast, auto-graded readiness check that covers all ten big ideas of 7th grade in ten questions. Perfect for day one or two of 8th grade. Each question maps to one standard and scores separately, so your class dashboard becomes a heatmap showing exactly which skills are solid and which need review. Not a test, a map. Randomized values. CCSS 7.RP, 7.NS, 7.EE, 7.G, 7.SP.
Students apply ratios, percentages, and budgeting skills in this fast-paced, team-based math competition. As co-founders of a vehicle startup, they calculate production costs, analyze sales offers, and race through 10 business cycles—boosting engagement through real-world math, strategy, and collaboration.
In this crossword-like puzzle, students will divide decimal numbers and find the answers to solve the puzzle. Each student will receive a different set of questions.
In this spooky Halloween-themed activity, students calculate the speed of different Halloween characters using the speed = distance ÷ time formula and determine who’s fastest in the crew. A fun and educational way to reinforce rate and proportional reasoning!
Interactive integer multiplication practice for Grade 7. Students multiply across all four sign combinations while a live sign grid fills in as they answer, turning the sign rules into a visual pattern they build themselves. Auto-graded, standards-aligned to 7.NS.A.2, with optional randomization so every student gets a unique problem set. Great for practice, remediation, and retakes.
