Lesson 4 — Which Way Is Better?

Age: Grades 1–3 (ages 6–9) Duration: 15–20 minutes Format: Web game (play right away, no prep needed) Concept: Algorithm — the same task can have many algorithms, and you can compare them (faster/simpler)

Learning Objective

Kids find the SHORTEST path — one task, many solutions, and the better one uses fewer commands (the idea of efficiency).

Do It Together (Parent-Child Co-participation)

Ask, "Is there another way? Which uses fewer commands?" — great programmers don't stop at "it works"; they ask "is there a better way?"
