Lesson 4 — Debug the Round Count

Age: Grades 1–3 (ages 6–9) Duration: 15–20 minutes Format: Web game (play right away, no prep needed) Concept: Debugging loops — check and fix a wrong number of rounds

Learning Objective

Kids look at a repeating path and turn it into a loop in their head — connecting loops to robot commands (getting ready for Blockly).

Do It Together (Parent-Child Co-participation)

Afterwards, point out that the commands were "up-right" repeated 3 times — written as a loop that's 🔁3×(⬆️➡️). Much shorter!
