Properties of 2D Shapes
Students will describe 2D shapes by the number of sides and corners (vertices) they have.
About This Topic
Students will describe 2D shapes by the number of sides and corners (vertices) they have.
Key Questions
- How many sides and corners does each shape have?
- Can two different shapes have the same number of sides?
- How does knowing the properties of a shape help us name it?

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.
