Recognize multiplication as commutative and associative.
Clarifications:
Essential Understandings
Concrete:
- Use manipulatives to show how related problems (e.g., 2 × 3 = 3 × 2) result in the same product.
- Use manipulatives to show how grouping of factors will not change the end product when working with more than 2 factors {e.g., (2×3)×4 = 2×(3×4)}.
- Compare related problems (2 × 3 = 3 × 2).
- Compare related problems {(2×3)×4 = 2×(3×4)}.
- Use the symbols: ×, =, (, and related concepts.

Cluster:
Understand properties of multiplication and the relationship between multiplication and division. (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.
