Common Core For Grade 3

Videos, examples, and solutions to help Grade 3 students learn to understand a fraction as a number on the number line; represent fractions on a number line diagram.

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.

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.

Common Core: 3.NF.2

### Suggested Learning Target

**3.NF.2.b - Fractions on the Number Line**

This video represents fractions on the number line by first defining how many parts make 1 whole. Then naming each part a fractional unit and counting that many units.**3 nf 2ab**

The Common Core State Standards (CCSS) videos are designed to support states, schools, and teachers in the implementation of the CCSS. Each video is an audiovisual resource that focuses on one or more specific standards and usually includes examples/illustrations geared to enhancing understanding. The intent of each content-focused video is to clarify the meaning of the individual standard rather than to be a guide on how to teach each standard although the examples can be adapted for instructional use.

- I can explain and show how 1/b can be represented on a number-line in two ways (1) as a number that is located a distance of 1/b to the right of 0, and (2) as the size of each of the parts when a whole is partitioned into b equal parts.
- I can explain and show how a/b can be represented on a number line in two ways: (1) as a number that is located a distance a/b to the right of 0, and (2) as the size of a parts when a whole is partitioned into b equal parts.
- I can represent a unit fraction (1/b) on a number line between 0 and 1.
- I can represent any fraction (a/b) on a number line.
