Three-Dimensional Shapes (Solids)
Identifying and describing common 3D shapes (cubes, cuboids, cylinders, spheres, cones) and their nets.
Key Questions
- Differentiate between 2D and 3D shapes based on their dimensions.
- Predict which 2D shapes would form the faces of a given 3D object.
- Design a net for a simple 3D shape like a cube or cuboid.

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.
