Properties of 2D Shapes
Students will identify and describe properties of triangles, quadrilaterals, pentagons, hexagons, and other polygons by the number of sides and corners.
Key Questions
- What properties do all quadrilaterals share, and how do specific quadrilaterals differ?
- How can you sort a group of shapes by the number of sides or corners?
- What makes a shape a polygon, and what shapes are NOT polygons?

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.
More in Geometry: 2D Shapes and Angles
Understanding Right Angles
Students will identify right angles in shapes and in the environment, and use a set square to test whether an angle is a right angle.

Comparing Angles: Greater Than and Less Than a Right Angle
Students will compare angles to a right angle and classify them as greater than, equal to, or less than a right angle.

Line Symmetry
Students will identify lines of symmetry in 2D shapes and complete symmetrical figures using folding and drawing.
