Age: Grades 4–6 (ages 9–12) Duration: 20–25 minutes Format: Web game — drag blocks to write a real program (Blockly) Concept: Block Programming — writing a nested loop for the first time (repeat inside repeat)

Learning Objective

Kids write their first nested loop (a repeat inside a repeat) — walking around a square garden in just 4 blocks.

Do It Together (Parent-Child Co-participation)

Ask your child to explain "what does the outer loop do, and the inner one?" If they can explain it, they've got nested structure.
