CODE KALEIDOSCOPE

Duration

45-60 minutes.

Starter 8 min, guided build 25 min, reflection 12 min.

Learning Aim

• Variables: segments, size, colour theme.
• Input and output in an interactive system.
• Selection and iteration in visual pattern generation.

Materials

• PC and internet connection.
• Projected teacher demo screen.
• Printed challenge and reflection sheets.

1. I Do

Model one challenge and one target concept while thinking aloud.

Use the live model panel to show how a control changes the code vocabulary.

2. We Do

Complete the next challenge together, using cold call questions to check understanding.

Pause for short compare-and-share moments before students continue independently.

3. You Do

Students complete challenge levels in sequence and mark each as complete.

Students explain one design choice and one code-side variable change using the reflection sheet.

Lesson Overview Sheet

One-page teacher plan with timing and concept checkpoints.

Challenge Worksheet

Structured student worksheet linked to the 8 challenge levels.

Reflection Sheet

Simple prompts for evaluating creative and computational decisions.

Support Route

• Keep shape fixed and change one variable only.
• Use starter code view and concept tooltips frequently.
• Pair verbal sentence frames with visual outputs.

Core Route

• Complete challenge levels 1-6 in order.
• Compare two outputs and justify preferred design.
• Track progress using completion markers.

Stretch Route

• Use dashes/ribbon plus new shapes for a final composition.
• Predict the output before changing settings.
• Explain changes using variable, selection, and loop terms.
