Demonstrate or identify appropriate measuring techniques.
Clarifications:
Essential Understandings
Concrete:
- Identify tools to measure length (ruler, yardstick).
- Identify the beginning and end point of an object’s length.
- Identify and demonstrate that the beginning of an object should be lined up at the zero point on the measuring tool (ruler, yardstick) to measure length.
- Identify and demonstrate that the length of the object is based on the number of units from the object’s beginning point to its endpoint.
- Using a visual representation of an object with its beginning point lined up at the zero point on the visual representation of a ruler, determine the length of the object based on the number of units from the object’s beginning point to its endpoint.
- Understand the following concepts and vocabulary of ruler, yardstick, length, endpoint, zero point, beginning point.

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.
