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.
Remarks/Examples
Examples of Opportunities for InDepth FocusThe Pythagorean theorem is useful in practical problems, relates to gradelevel work in irrational numbers and plays an important role mathematically in coordinate geometry in high school.
