Essential Understandings
Concrete:
- Given two models of base ten blocks on a place value chart, compare the value of the same digit used in different place value positions (e.g., 23 where 2 represents 2 tens and 42 where 2 represents 2 ones).
- Recognize the value of a digit based on its place in a two-digit number (e.g., the 2 in 25 represents 2 tens or 20).
- Compare the value of the same digit used in different place value positions (e.g., 23 where 2 represents 2 tens and 42 where 2 represents 2 ones).

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. |
