🐍 Code Logic

Pupils practise problem solving through "Code Logic": AND, OR and variables.

Lesson guide

1. 1. Hook · 5 min

   Show the 🐍 mission title and read the opening: "score = 5, then score = score + 3. Score?". Take three quick guesses.

2. 2. Model · 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. 3. Do · 10 min

   Pairs work through the 3 steps on screen or on the printed sheet. Circulate and ask "why?"

4. 4. Discuss · 10 min

   Use two or three of the discussion questions. Ask pairs to share different answers, not just correct ones.

5. 5. Reflect · 5 min

   Exit ticket: one sentence on how they used problem solving today.

Discussion questions

• What was the hardest choice in "Code Logic", and why?
• score = 5, then score = score + 3. Score — explain your reasoning to a partner.
• 'If sunny AND warm then beach'. Sunny but cold — explain your reasoning to a partner.
• 'If cake OR ice cream then happy'. Only cake — 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.
