Naming and Recognising 3D Objects
Students identify and measure different types of angles (acute, obtuse, right, straight, reflex) using a protractor.
Key Questions
- Can you find an object in the classroom that is shaped like a cube?
- What is this shape called? Can you roll it — why or why not?
- How is a sphere different from a cylinder?

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.
