Composing 2D Shapes
Composing simple shapes to form larger, more complex geometric figures.
Key Questions
- How many triangles does it take to build a single square?
- Can we use different shapes to build the exact same larger design?
- Design a new shape by combining two or more basic shapes.

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.
