Recognize addition as commutative.
Clarifications:

Essential Understandings

Concrete:

  • Use manipulatives to represent addends in two related addition equations to show that changing the order of the addends does not change the sum.
  • e.g. manipulatives
Representation:
  • Model two related addition equations (e.g., 1 + 5 = 6 and 5 + 1 = 6) by coloring squares on grid paper to represent each addend with a different color to show that changing the order of the addends does not change the sum.
  • Identify pairs of equations that demonstrate the commutative property (e.g., match 2 + 6 = 8 with 6 + 2 = 8).
  • Understand the following concepts, symbols, and vocabulary: addition, plus, equal, addends, sum, order.
General Information
Number: MAFS.1.OA.2.AP.3a
Category: Access Points
Cluster: Understand and apply properties of operations and the relationship between addition and subtraction. (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.
