1 - Getting Started ~3 mins
Our little robot is stuck on its start square, and the flag is waiting. It cannot guess the way. How do we give it instructions so it can get there?
2 - Steps the Robot Can Follow ~5 mins
Today's words: algorithm — our list of moves in the right order, like forward, forward, turn right, forward. Bug — a wrong step that sends the robot the wrong way.
A turn stays on the same square — only forward steps onto the next one. Watch one short route. Will the robot stop on the flag?
3 - Plan the Route on the Board ~6 mins
Help plan a short route on the board. Call out the next move: forward, turn left or turn right. Your teacher will drag the steps and press run. Before go, put your hands up if you think the robot will land on the flag.
Plan a route to the flag
4 - Program the Floor Robot ~14 mins
In your group:
- Choose a start and a target. Lay your arrow cards in order beside the mat.
- Say the moves out loud. Predict where the robot will stop.
- Enter the moves and press go.
- If it misses, change the wrong card, then put the same fix on the robot, and try again.
- Leave the final working cards in place for your journal.
5 - Record Our Moves ~6 mins
On your Investigation Journal page:
- Copy the moves from your arrow cards in order (arrows are enough).
- Mark yes or no: did the robot reach the target?
- If you fixed a bug, circle the step you changed.
