Classify objects into given categories; count the numbers of objects in each category and sort the categories by count.
General Information
Subject Area: Mathematics
Grade: K
Domain-Subdomain: Measurement and Data
Cluster: Level 2: Basic Application of Skills & Concepts
Cluster: Classify objects and count the number of objects in each category. (Supporting 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.
