Shapes and Objects in Our Environment
Students identify and calculate vertically opposite angles and angles formed by parallel lines and a transversal.
Key Questions
- Can you find three shapes in our classroom and tell me their names?
- What shape is the window? What shape is the door?
- Where can you find a sphere shape in everyday life?

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.
