Essential Understandings

Concrete:

  • Recognize corresponding points and sides in figures (e.g., match concrete examples of congruent shapes, match concrete examples of similar shapes).

  • Understand the following concepts and vocabulary: figures, congruent, similar.
  • Describe circles, squares, rectangles, and triangles by telling about their shape, sides, lines, and angles.

Date Adopted or Revised: 05/14 Cluster: Understand congruence and similarity using physical models, transparencies, or geometry software. (Major 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.
