Properties of Squares and Rectangles
Students will derive and apply the formula for the sum of interior angles of any polygon, and calculate individual interior/exterior angles of regular polygons.
Key Questions
- What are the properties of a square in terms of its sides and angles?
- How is a rectangle similar to and different from a square?
- Can you identify squares and rectangles in a collection of shapes and explain your reasoning?

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.

Angles: Types and Properties
Students will review and extend their knowledge of angle types (acute, obtuse, reflex) and properties of angles on a straight line and at a point.

Perpendicular and Parallel Lines
Students will identify and apply properties of angles formed when a transversal intersects parallel lines (corresponding, alternate, interior angles).

Drawing Perpendicular and Parallel Lines
Students will use compass and straightedge to construct perpendicular bisectors, angle bisectors, and parallel lines.

Lines of Symmetry
Students will apply angle properties of triangles (sum of angles, exterior angle theorem) and classify them by sides and angles.

Properties of Triangles and Quadrilaterals
Students will investigate and apply the properties of various quadrilaterals (parallelograms, rhombuses, trapeziums, kites) to solve problems.
