Vocabulary
Common Mistakes
- Confusing Area and Perimeter formulas

- Using wrong units (e.g., cm instead of sq cm for Area)
- Incorrect decomposition
- Misidentifying side lengths
- Multiplication errors
- Forgetting to add areas
Differentiation
Discussion Questions
- What is the difference between Area and Perimeter?
- Can two rectangles have the same perimeter but different areas?
- Why do we use 'square' units for area?
- How many ways can you split an L-shape into rectangles?
- Does the way you split an L-shape affect its total area?
- Why is decomposing helpful for finding area?
- When might you encounter L-shapes in real life?
Extension Activities
- Measure the classroom floor area.
- Design a garden with a specific perimeter.
- Create art using only rectangles of specific areas.
Parent Tip
Use blocks to build an L-shape and find its area.
