Lesson Plan: Quadrilaterals Mathematics • 3rd Grade
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to define quadrilaterals and classify them as squares, rectangles, trapezoids, rhombuses, or none of these.
Objectives
Students will be able to
- define a quadrilateral, square, rectangle, rhombus, trapezoid, and parallelogram,
- identify the above shapes based on their properties,
- recognize quadrilaterals that are none of the above,
- state the properties of the above quadrilaterals,
- describe how squares, rectangles, and rhombuses are special types of parallelograms and how squares are special types of rectangles.
Prerequisites
Students should already be familiar with
- right angles and their notation,
- parallel and perpendicular lines (not their notation).
Exclusions
Students will not cover
- using the notation for lines, line segments, rays, congruence, parallel lines, and perpendicular lines,
- classifying quadrilaterals by the properties of their diagonals,
- the hierarchy of quadrilaterals.
