Cross-Sections of 3D Figures
Students will describe and draw the two-dimensional cross-sections of three-dimensional objects.
Key Questions
- Visualize and describe the shape of a cross-section formed by slicing a cube at different angles.
- Predict the shape of a cross-section of a cylinder when cut parallel and perpendicular to its base.
- Analyze how the orientation of a plane affects the resulting cross-section of a cone.

Planning templates for Mathematics
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.
