Essential Understandings
Concrete:
- Use base ten blocks to represent two numbers up to 100.
- Use matching, starting with the ‘tens’, to determine which set of base ten blocks is greater than, less than, or equal to the other set.
- Use a visual representation of base ten blocks to represent two numbers up to 100.
- Use matching of visual representations of base ten blocks, starting with the ‘tens’, to determine which set of base ten blocks is greater than, less than, or equal to the other set.
- Recognizing the value of a digit, in a two-digit number, based on its place on a place value chart (e.g., the 2 in 25 represents 2 tens or 20), compare two numbers starting with the digit in the ‘tens’ place.
- Demonstrate an understanding of the following concepts, symbols, and vocabulary: greater than, less than, equal to.

Cluster:
Understand place value. (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. |
