Measure the difference in standard length units.
Clarifications:
Essential Understandings
Concrete:
- Recognize that when we compare lengths we want to answer “How much longer or shorter is object 1 than object 2?”
- Given a word problem, use one inch measurement linking cubes to compare the length of one object from the word problem, to the length of another object from the word problem, and determine how many cubes (inches) longer or shorter one object is than the other object.
- Create a visual representation of the lengths of the objects in a word problem to determine how much longer or shorter one object is than the other object.
- Understand the following concepts and vocabulary of longer, shorter, inches, feet, difference, units.

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.
