Investigation
Think about getting ready for school. What do you do first? What comes next? Could you tell a robot how to do it, step by step?
Watch and listen to the steps for brushing teeth. What happens when we mix two steps up?
Look at the path on the board. Call out which step should come first, next and last. We move the blocks on the board as you call them. Then we press run and see if the order was right.
Reach the flag in order
In your group:
- Put the picture-step cards into the right order.
- Say the steps out loud together.
- Choose one person to be the robot.
- Read one card at a time. The robot follows each step exactly — no guessing and no extra moves.
