Why?
“The simplest version of a measurement model is the number line. This is the most useful model in all of mathematics! In fact, the number line is the only model that continues to work as elementary mathematics progresses through whole numbers, fractions, and on to negative, rational, and irrational numbers.”

Represent whole numbers as lengths from 0 on a number line diagram with equally spaced points corresponding to the numbers 0, 1, 2, ..., and represent whole-number sums and differences within 100 on a number line diagram.
Use the four operations to solve word problems involving distances, intervals of time, liquid volumes, masses of objects, and money, including problems involving simple fractions or decimals, and problems that require expressing measurements given in a larger unit in terms of a smaller unit. Represent measurement quantities using diagrams such as number line diagrams that feature a measurement scale.
Understand a fraction as a number on the number line; represent fractions on a number line diagram.
