Determine whether the product will increase or decrease based on the multiple using visual fraction models.
Clarifications:
Essential Understandings
Concrete:
- Use fraction manipulatives and begin with single groups of a number (e.g., 1 × 5, 1 × 6, 1 × 7) to show the product will remain the same.
- Use fraction manipulatives to model groups of numbers greater than 1 (e.g., 2 × 5, 3 × 6, 4 × 7) to show the product will increase.
- Use fraction manipulatives to model groups of a numbers less than 1 (e.g., 1/2 × 6, 1/2 × 4) to show the product will decrease.
- Recognize when a number is multiplied by a number less than one (e.g., 1/2, 3/4, 5/6, 0) the product will decrease.
- Recognize when a number is multiplied by a number greater than one, the product will increase.
- Understand the following vocabulary: product, increase, decrease, and fraction.

Cluster:
Apply and extend previous understandings of multiplication and division to multiply and divide fractions. (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.
