Understand a fraction as a number on the number line; represent fractions on a number line diagram.

3.NF.2a:

Number And Operations - Fractions

Develop Understanding Of Fractions As Numbers.

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.

4.NF.2:

Number And Operations - Fractions

Extend Understanding Of Fraction Equivalence And Ordering.

Compare two fractions with different numerators and different denominators, e.g., by creating common denominators or numerators, or by comparing to a benchmark fraction such as 1/2. Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the results of comparisons with symbols >, =, or <, and justify the conclusions, e.g., by using a visual fraction model.
