 Number: MAFS.4.NBT.1.AP.2c Category: Access Points Cluster: Generalize place value understanding for multi-digit whole numbers. (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.
