Excerpt 3: Cluster K.CC.C: Compare numbers. (Pages 17-20)

Description: Explanations and examples of how to implement the Counting & Cardinality standards in Kindergarten. Identify whether the number of objects in one group is greater than, less than, or equal to the number of objects in another group, e.g., by using matching and counting strategies. Students begin comparing numbers of objects in two groups using strategies such as matching. Matching strategies allow students to pair objects and see if there are any extra (i.e., more) and to concretely determine "which is more" and "which is less".
