Identify an angle in a two-dimensional figure.


Essential Understandings


  • Use two-dimensional (2-D) manipulatives, such as pattern blocks and attribute shapes, to identify angles.
  • Use a visual representation of a two-dimensional (2-D) shape to identify angles.
  • Understand the following concepts, symbols, and vocabulary: angle and degree.

Number: MAFS.4.G.1.AP.1c 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.
