Area of Composite Shapes
Students will calculate the area of composite shapes by decomposing them into simpler polygons and circles.
Key Questions
- Explain how any polygon can be broken down into simpler shapes to find its area.
- Justify the process of subtracting areas when dealing with shapes with 'holes'.
- Design a strategy for calculating the area of an irregularly shaped garden.

5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
unit plannerMath Unit
Plan a multi-week math unit with conceptual coherence: from building number sense and procedural fluency to applying skills in context and developing mathematical reasoning across a connected sequence of lessons.
rubricMath Rubric
Build a math rubric that assesses problem-solving, mathematical reasoning, and communication alongside procedural accuracy, giving students feedback on how they think, not just whether they got the right answer.
