MA.3.FR.1.1

Represent and interpret unit fractions in the form 1/n as the quantity formed by one part when a whole is partitioned into n equal parts.

Examples

begin mathsize 11px style 1 fourth end style can be represented as begin mathsize 12px style 1 fourth end style of a pie (parts of a shape), as 1 out of 4 trees (parts of a set) or as begin mathsize 12px style 1 fourth end style on the number line.

Clarifications

Clarification 1: This benchmark emphasizes conceptual understanding through the use of manipulatives or visual models. 
Clarification 2: Instruction focuses on representing a unit fraction as part of a whole, part of a set, a point on a number line, a visual model or in fractional notation.

Clarification 3: Denominators are limited to 2, 3, 4, 5, 6, 8, 10 and 12.
