Measurement and Dimensional Analysis · Term 2

Volume and Surface Area of Composite Solids

Students will calculate the volume and surface area of objects composed of two or more simple 3D shapes.

Key Questions

  1. Justify the process of deconstructing composite solids for measurement calculations.
  2. Analyze why overlapping areas are subtracted when calculating the surface area of composite solids.
  3. Design a composite solid with a specific volume or surface area constraint.

lesson plan

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 planner

Math 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.

rubric

Math 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.
