Engage students in meaningful, real-world math with this Ratios and Proportions Project: Mixing Paint. In this performance-based task, students apply ratio reasoning, unit rates, and proportions to analyze and create paint mixtures while justifying their mathematical thinking.

This project challenges students to work through multi-step, real-life scenarios, encouraging deeper understanding and problem-solving rather than simple computation. Students must write ratios, solve proportions, interpret tables, and explain errors in reasoning—all while connecting math to a practical context.

A complete answer key is included, making this an easy-to-implement project for classwork, enrichment, or assessment.
