Clarifications:

Essential Understandings

Concrete:

  • Use base ten manipulatives to divide numbers.
  • Match characteristics of irrational and rational numbers.

Number: MAFS.8.EE.1.AP.2e Category: Access Points
Date Adopted or Revised: 07/14 Cluster: Work with radicals and integer exponents. (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.
