Introduction to 3D Objects and Nets
Students will identify common 3D objects and draw their nets to visualize their surfaces.
Key Questions
- Explain how the nets of 3D objects help us derive the formulas for their surface area?
- Differentiate between a prism and a pyramid based on their nets.
- Construct the net for a given 3D object.

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.
