Lesson Plan

1Opening (5 min)

Review previous day's learning about partitioning shapes

💭 Review Question: Can you show me how you divide a shape into equal parts?
2Teaching (12 min)

Explore the concept of equal areas in shape partitions

📌 Key Talking Points:
  • Equal parts mean the same size and shape
  • Cutting a shape doesn't change its total area
  • Different ways to create equal parts
💬 Discussion Questions:
  • How can we check if parts are truly equal?
  • What happens if we cut a shape differently?
3Activity: Equal Area Investigations (14 min)
hands-on exploration

Students will cut shapes and verify equal areas

📝 Instructions:
  1. Fold paper into equal sections
  2. Cut along fold lines
  3. Compare and verify each piece
  4. Trace and overlay pieces to confirm
🔄 Variations:

Simpler: Use pre-drawn lines for cutting

Challenge: Create own division strategies

4Closing (4 min)

Summarize key learning about equal areas

📝 Review Questions:
  • What makes parts truly equal?
  • How can we check our work?

Coming up: Tomorrow we'll explore partitioning different polygon shapes
