Strand: NUMBER AND OPERATIONS - FRACTIONS (3.NF)

Develop understanding of fractions as numbers. Denominators are limited to 2, 3, 4, 6, and 8 in third grade.

Standard 3.NF.2

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

• Closest to 1/2
In this task students are given a number line and a choice of fractions. They must identify which of the choices is closest to 1/2.
• Comparing Fractions with Lines
In this game students are given 2 fractions and they must determine whether one is less than, greater than or equal to the other.
• Equivalent Fractions Finder
Students doing this lesson will visually experiment with the relationship between the value of fractions and areas within a square or a circle. In doing so they will practice simplifying fractions and compare fractions.
• Find 1
The purpose of this task is to assess whether students understand fractions as being built from unit fractions and whether they can accurately locate fractions on the number line.
• Find 1 Starting from 5/3, Assessment Variation
This task requires that students understand a fraction as a number on the number line and represent fractions on a number line diagram.
• Find 1/4 Starting from 1, Assessment Version
This task requires that students understand a fraction as a number on the number line and represent fractions on a number line diagram.
• Find 7/4 starting from 1, Assessment Variation
This task requires that students understand a fraction as a number on the number line and represent fractions on a number line diagram.
• Finding 2/3
This simple-looking problem reveals much about how well students understand unit fractions as well as representing fractions on a number line.
• Grade 3 Mathematics Module 5: Fractions as Numbers on the Number Line (EngageNY)
In this 35-day Grade 3 module, students extend and deepen second grade practice with "equal shares" to understanding fractions as equal partitions of a whole. Their knowledge becomes more formal as they work with area models and the number line.
• Locating Fractions Greater than One on the Number Line
Given a number line and a list of fractions, students must mark and label each fraction on the line.
• Locating Fractions Less than One on the Number Line
In every part of this task, students must treat the interval from 0 to 1 as a whole, partition the whole into the appropriate number of equal sized parts, and then locate the fraction(s) on a number line.
• USBE Core Guide for Domain: Number and Operations - Fractions (3NF2)
This math guide provides academic vocabulary, instructional strategies, teacher resources, and assessment tasks for the Number and Operations - Fractions domain.
• Which is Closer to 1?
In this problem students are given 2 fractions and asked to determine which of them is closest to 1.
