Clarifications:
Essential Understandings
Concrete:
-
To build fluency:
- Make a set of objects within 10.
- Add “more” to a set or “take from” or “take apart” a set.
- Recount the set to get a sum or a difference within 10.
- After repeated exposure to concrete and representational addition and subtraction, students will become flexible, efficient, and accurate with addition and subtraction facts within 10 without manipulatives.

Cluster:
Add and subtract within 20. (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.
