๐ค Robot Treasure Route
Pupils practise problem solving through "Robot Treasure Route": Give precise commands and repair a wrong turn.
Lesson guide
1. Hook ยท 5 min
Show the ๐ค mission title and read the opening: "Which instruction is clearest for a grid robot?". Take three quick guesses.
2. Model ยท 5 min
Think aloud through the first step together. Use Cog the Owl's line as your prompt: "Good thinking. Show me the why."
3. Do ยท 10 min
Pairs work through the 5 steps on screen or on the printed sheet. Circulate and ask "why?"
4. Discuss ยท 10 min
Use two or three of the discussion questions. Ask pairs to share different answers, not just correct ones.
5. Reflect ยท 5 min
Exit ticket: one sentence on how they used problem solving today.
Discussion questions
- What was the hardest choice in "Robot Treasure Route", and why?
- Which instruction is clearest for a grid robot โ explain your reasoning to a partner.
- A robot turns left instead of right. What should you do โ explain your reasoning to a partner.
- Does a robot always know what you meant โ explain your reasoning to a partner.
- Where could you use problem solving outside school this week?
- If you did this again, what would you change?
Adapting it
Support: Read prompts aloud, pair with a confident partner, and accept spoken or drawn answers for writing steps.
Stretch: Ask pupils to create their own extra step for a partner and explain the correct answer.
