Setup
Gather grid map, arrow cards, toy rover and clear a small work surface. Read the Lost Rover Recovery mission aloud, then place the supplies where children can choose and compare them safely.
Activity
- Study the grid map and predict a safe path for the rover to reach home base.
- Arrange arrow cards into a step-by-step program that will guide the rover along that path.
- Run the rover through the sequence and discover it crashes into an obstacle or misses a turn, then debug the cards.
- Celebrate the rover's successful homecoming by walking a partner through the final working program.
Done when: Children complete the core mission and the rover's successful homecoming by walking a partner through the final working program.
Materials
Masking tape for a floor grid, a wind-up or rolling toy rover, arrow direction cards, small blocks as obstacles
