## CCSS.Math.Content.3.NF.A.2 - Understand a fraction as a number on the number line; represent fractions on a number line diagram.

## CCSS.Math.Content.3.NF.A.2.a - Represent a fraction 1/b on a number line diagram by defining the interval from 0 to 1 as the whole and partitioning it into b equal parts. Recognize that each part has size 1/b and that the endpoint of the part based at 0 locates the number 1/b on the number line.

## CCSS.Math.Content.3.NF.A.2.b - Represent a fraction a/b on a number line diagram by marking off a lengths 1/b from 0. Recognize that the resulting interval has size a/b and that its endpoint locates the number a/b on the number line.
