Lesson Plan: Composing and Decomposing 2D Shapes Mathematics • 1st Grade
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to use 2D shapes to make a composite shape and decompose composite shapes into smaller shapes.
Objectives
Students will be able to
- Understand that shapes can be combined to make new shapes,
- Identify the shapes used to make composite shapes,
- Make composite shapes from 2D shapes.
Prerequisites
Students should already be familiar with
- recognising common 2D shapes,
- the number of sides and vertices in common 2D shapes.
Exclusions
Students will not cover
- 3D shapes.
