Essential Understandings
Concrete:
- Introduce the ones block as a representation of the value one.
- Introduce the tens block as a representation of the value ten. (Ex: show that 10 of the ‘ones block’ is equivalent to one of the ‘ten block’).
- Using one ‘tens block’, add ‘ones blocks’ in order to build representations of 11 to 15.
- Recognize a set of 10 as 10 without counting. (Ex: a base ten block represents 10 ones)
- Identify a visual representation of the numbers 11-15, using a ten block and ones blocks.

Cluster:
Work with numbers 11–19 to gain foundations for 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. |
