Lesson: Properties of 2D Shapes Mathematics • 1st Grade

In this lesson, we will learn how to analyze 2D shapes to see what features a shape always has and what features it sometimes, or never, has.

Lesson Plan

Students will be able to

  • describe the properties of two-dimensional shapes,
  • identify common 2D shapes by their attributes,
  • sort 2D shapes according to their attributes,
  • investigate and describe the defining and nondefining attributes of 2D shapes.
