Essential Understandings
Concrete:
- Using 12 one-inch measurement linking cubes, linked together to make one foot, decompose 1 foot into 12 inches.
- Within the same system of measurement, identify the shorter or longer unit—inches are shorter than feet.
- Understand that longer units (a foot) are made up of multiple copies of a shorter unit (12 inches).
- Given a visual representation of one foot, decompose into 12 inches.
- Understand that multiple units make up a larger unit of measure (12 inches in 1 foot).
- Understand the following concepts and vocabulary of inches, foot, units, decompose.

Cluster:
Measure and estimate lengths in standard units. (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. |
