Identify figures that have a line of symmetry.

Clarifications:

Essential Understandings

Concrete:

  • Fold figures along drawn lines to determine if the figures are symmetrical.
  • Sort figures into categories: symmetrical and non-symmetrical.
Representation:
  • Given a picture, select shapes that have a line of symmetry already drawn.
  • Given a picture, select shapes that are symmetrical.

Number: MAFS.4.G.1.AP.3a Category: Access Points
Date Adopted or Revised: 06/14 Cluster: Draw and identify lines and angles, and classify shapes by properties of their lines and angles. (Additional Cluster)

Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.
