Volume and Surface Area of Composite Solids
Students calculate the volume and surface area of objects made from combining two or more simple 3D shapes.
Key Questions
- How can we break down a composite solid into simpler shapes to calculate its volume and surface area?
- Design a complex object made from prisms and cylinders, then calculate its total volume.
- Critique different strategies for calculating the surface area of a composite solid.

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.
