In Year 2, robot programs get longer and the grid gets busier. Children plan routes around rocks, compare programs to find one that works, and build their own programs one arrow at a time.
Apa yang akan dipelajari anak anda
- Read a program and predict what it does

Plan, build, test
Good programmers plan first. Encourage your child to trace the route with a finger before tapping any arrows. After pressing Run, watching the robot move shows immediately whether the plan worked — and where it went wrong if it didn’t.
