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 — using the if block in real code for the first time

Learning Objective

Kids use the if block in real code for the first time — and understand WHY if exists: ONE program must pass several maps where the rocks sit in different places (or nowhere). A fixed walk isn't enough; the program must "decide for itself" based on what's ahead.

Do It Together (Parent-Child Co-participation)

Connect it back: those if-then quizzes are now blocks your child actually uses — go hunt for more ifs around the house.
