Fluently multiply and divide within 20.
Clarifications:
Essential Understandings
*Fluency means: accurately, efficiency (using a reasonable number of steps and time) and flexibility (using a variety of strategies) Taken from: Number Talks by Sherry Parrish
Concrete:
- Use arrays to show equal groups of manipulatives.
- Use repeated addition/skip counting to find the total number of objects within an array up to 20.
- Use manipulatives to divide a given number up to 20 equally into a number of groups or groups of an equal number.
- Use pictures/drawings to represent arrays showing equal groups.
- Write an equation to express the total number of objects as a sum of equal addends (repeated addition).
- Use pictures/drawings to divide a given number up to 20 equally into a number of groups or groups of an equal number.

Cluster:
Multiply and divide within 100. (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.
