Area and Perimeter

**Fractions**

**3.NF.A.1: Understand a unit fraction as the quantity formed by one part when a whole is partitioned into (2, 3, 4, 6, and 8) equal parts.**

__EXAMPLES__

Area models:

What fraction names the shaded part?

Which of the following shapes are partitioned into fourths?

Number Lines:

What fraction names point A on the number line?

Locate and draw point F on the number line to represent the fraction 1/2

What fraction does the shaded bar represent?

**3.NF.A.2.a: Describe the numerator as representing the number of pieces being considered.**

__EXAMPLES__

What does the numerator 3 represent in the given fraction?

The model shows one whole. Shade in ¾ of the model.

**3.NF.A.2.b: Describe the denominator as the number of pieces that make the whole.**

__EXAMPLES__

Carson rode his bike along a bike trail that was ¼ of a mile long. What image represents the length of the bike trail in miles?

Which picture shows a number line partitioned into eighths?

**3.NF.A.3.a: Represent fractions on a number line. Understand the whole is the interval from 0 to 1.**

__EXAMPLES__

What fraction names point A on the number line?

Marcia drew a number line partitioned into 8 equal parts. What fraction names point B on the number line?

**3.NF.A.3.b: Represent fractions on a number line. Understand the whole is partitioned into equal parts.**

**3.NF.A.3.c: Understand a fraction represents the endpoint of the length a given number of partitions from 0**

__EXAMPLES__

What fraction names point A on the number line?

Which point on the number line represents 2/3?

**3.NF.A.4: Demonstrate that two fractions are equivalent if they are the same size, or the same point on a number line.**

__EXAMPLES__

Given two images, determine whether or not the fractions are equivalent.

Image may be a number line partitioned two different ways or a fraction bar partitioned two different ways.

**3.NF.A.5: Recognize and generate equivalent fractions using visual models, and justify why the fractions are equivalent.**

__EXAMPLES__

Which of these fractions are equivalent? 4/8, 1/2, 6/8, 1/3, 2/4 How do you know?

Students are given various fraction cards to place on a number line. Discuss equivalence.

Students use note cards to create fractions with various denominators.

**3.NF.A.6: Compare two fractions with the same numerator or denominator using the symbols >, = or <, and justify the solution**
