Volume of Rectangular and Triangular Prisms
Students will calculate the volume of rectangular and triangular prisms using the base area times height principle.
Key Questions
- Why can the volume of any right prism be found by multiplying the area of its cross-section by its length?
- How does the concept of volume differ from the concept of surface area in practical applications?
- Predict the change in volume if the base area of a prism is doubled while its height is halved.

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.
