Code Kaleidoscope Lesson Overview

Lesson Intent

Use generative pattern making to introduce Python concepts in a creative and low-pressure way.

Timing

• Starter and demo: 8 minutes
• Guided challenge build: 25 minutes
• Reflection and discussion: 12-20 minutes

Success Criteria

• Learners can explain one variable they changed and the visual impact.
• Learners can identify at least two concept labels in the live model.
• Learners can complete at least one challenge with a short reflection.

Teacher Prompts

• What stayed the same and what changed?
• Which line in the live model changed when you adjusted this setting?
• How does increasing segments affect repetition?

Cold Calling Questions

Use short, low-stakes questions to check understanding during the I Do and We Do sections.

• What variable did I just change?
• Which part of the pattern changed on the canvas?
• What do you predict will happen if I increase the segments?
• Which code concept are we seeing here: input, variable, selection or loop?
• What stayed the same when I changed the shape?
• Why might changing one setting at a time help us test the design?

Plenary

Ask each learner pair to share:

1. Their preferred pattern and why.
2. One programming idea they used, for example variable, input or loop.
