Lesson Plan: Polygons and Nonpolygons Mathematics • Third Year of Primary School
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to define and identify polygons and nonpolygons and sort two-dimensional figures into polygons and nonpolygons.
Objectives
Students will be able to
- define polygons as closed shapes made of straight-line segments,
- recognize whether a given shape is a polygon,
- sort shapes into polygons and nonpolygons,
- identify attributes of polygons and nonpolygons,
- investigate whether the number of sides and the number of vertices in any given polygon are equal.
Prerequisites
Students should already be familiar with
- two-dimensional shapes,
- three-dimensional shapes,
- the difference between a line segment and a curve,
- the difference between closed and open shapes,
- triangles, quadrilaterals, pentagons, and octagons,
- the vertices and sides of a closed figure.
Exclusions
Students will not cover
- naming polygons,
- determining whether polygons are regular or irregular,
- concave polygons,
- congruence,
- angles.
