Students will meet a local chef to explore how multiplying mixed numbers helps scale recipes, conduct firsthand interviews to understand real cooking challenges, and create structured empathy maps grounded in direct user evidence to guide future solution design.

Students will synthesize chef and family interview data to identify patterns in recipe-scaling challenges, define a focused user-centered problem statement, and craft a clear “How Might We” question grounded in mathematical evidence about multiplying mixed numbers.

Students will generate and refine multiple solution concepts for helping real cooks accurately scale mixed-number recipes, using user research evidence and mathematical reasoning about multiplication as scaling to guide their decisions.

Students will build and refine a testable prototype of their Interactive Recipe Scaling Board, using real user feedback to improve how clearly mixed-number multiplication and scaling are explained for cooks.

Students will validate their Interactive Recipe Scaling Board and video series with a new user, document final feedback, and present their full culinary math design journey to an authentic audience, clearly connecting mixed-number multiplication strategies to real cooking needs.
