🧪 Final User Test with New Cook

Teams test their refined Interactive Recipe Scaling Board and scaled recipe with a new user (another chef, school staff member, or invited family volunteer who has not seen the project). The user uses the board to scale one mixed-number ingredient (e.g., 1 1/2 cups × 3 servings). Teams observe, record quotes on a feedback sheet, and note any confusion in the area model or algorithm steps. Students ask 2–3 prepared questions about clarity, accuracy, and usefulness.
