Curious Fractions is a classroom math game where students estimate fractional amounts by scaling recipes. Instead of drilling fraction arithmetic, students build intuition — figuring out how much flour or sugar they need when a recipe serves more or fewer people.
After each estimate, students explain their reasoning. An AI coach responds to what they actually said — naming strategies, asking questions about the reasoning, or suggesting a concrete next step. The AI is clearly labeled so students know when they're getting advice from a machine, and they can rate whether the coaching was helpful.
Teachers can customize the AI coaching prompts from a dashboard, and a Thinking Journal lets students see how their strategies evolve over time.
This project is a Curiosity Build — a small, opinionated project built during a hands-on session with Hypandra. The philosophy: building with AI surfaces questions that reading alone doesn't.
