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.1

Understand that a unit fraction has a numerator of one and a non-zero denominator.

• 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
This applet allows the student to test their understanding of fractions by naming an equivalent fraction to one shown on the screen.
• 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.
• Equivalent Fractions Pointer
This lesson will help students understand how to simplify and compare fractions as well as place them in order on a number line.
• Fraction Tutorials
This site provides tutorials and activities to help the student understand fractions.
• Fractions for Primary Students
Students will be introduced to fractions in this lesson by dividing a whole into parts and applying this understanding of fractions to fruit and other everyday objects.
• Getting to Know You
In this lesson plan students conduct a survey of their fellow students in order to understand the characteristics of the group. In doing so they will better understand fractions.
• 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.
• Halves, thirds, and sixths
The purpose of this task is for students to use their understanding of area as the number of square units that covers a region, to recognize different ways of representing fractions with area, and to understand why fractions are equivalent in special cases.
• Naming the Whole for a Fraction
The goal of this task is to show that when the whole is not specified, which fraction is being represented is left ambiguous.
• Single Fraction Finder
In this lesson students will practice dividing a whole into a fraction and visualize fractions on a number line.
• Single Fraction Pointer
This activity was designed to help students better understand fractions by practicing dividing a whole into a fraction and visualizing fractions on a number line.
• USBE Core Guide for Domain: Number and Operations - Fractions (3NF1)
This math guide provides academic vocabulary, instructional strategies, teacher resources, and assessment tasks for the Number and Operations - Fractions domain.
• What Fraction of this Shape is Red?
This Teaching Channel video shows how students can explore part and whole by creating pattern block designs. (4 minutes)
