Use counting on to find the sum of two addends.

Essential Understandings
Concrete:
- Using a full five frame, use counters to model addition problems by counting on [Ex: 5 +3 would be verbalized as: “five” (full frame), “6” (1 counter), “7” (one counter), “8” (one counter)]
- Using a ten block, use ones blocks to model addition problems by counting on [Ex: 10 +2 would be verbalized as: “ten” (ten block), “11” (ones block), “12” (ones block)]
- Using a drawing of a five frame, draw to model addition problems by counting on [Ex: 5 +3 would be verbalized as: “five” (full frame), “6” (1 counter), “7” (one counter), “8” (one counter)]
- Using a drawing of a ten block, draw ones blocks to model addition problems by counting on [Ex: 10 +2 would be verbalized as: “ten” (ten block), “11” (ones block), “12” (ones block)]

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.
