Category: Access Points
Date Adopted or Revised: 07/14
Cluster: Define trigonometric ratios and solve problems involving right triangles. (Geometry - 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.
