👨👩👧 Notes for parents
Age: Grades 4–6 (ages 9–12) Duration: 20–25 minutes Format: Web game (play right away, no prep needed) Concept: Variables — real programs use several variables at once, and one value can be computed from others
Learning Objective
Kids manage several variables at once and understand that one variable can be computed from others (change = paid − price).
Do It Together (Parent-Child Co-participation)
Open a pretend shop at home with real price tags. Your child is the cashier holding a 3-variable board; you're the customer (pay the wrong amount sometimes!).
