Standard #: MAFS.3.NF.1.3 (Archived Standard)

Test your fraction skills by answering questions on this site. This quiz asks you to simplify fractions, convert fractions to decimals and percentages, and answer algebra questions involving fractions. You can even choose difficulty level, question types, and time limit.

Students are given a number line scaled by fourths and ask to label the notches.

Students are given a familiar fraction and asked to generate an equivalent fraction justifying their reasoning.

Students are asked to divide two rectangles into fourths and then to consider how many fourths the two wholes represent.

Students compare two pairs of fractions and record their comparisons using the less than or greater than symbols.

Students compare two fractional parts of two different wholes.

Students determine whether or not fractions are equivalent.

Illustrations that can be used for teaching and demonstrating fractions. Fractional representations are modeled in wedges of circles ("pieces of pie") and parts of polygons. There are also clipart images of numerical fractions, both proper and improper, from halves to twelfths. Fraction charts and fraction strips found in this collection can be used as manipulatives and are ready to print for classroom use.

The students will receive paper pizzas that are divided into different fractional parts. They will decorate their pizza, and then make equal trades with classmates to explore equivalence of fractions.

In this lesson students will make initial discoveries about fractions. Students will work together to explain and record the discoveries they make while using manipulatives to explore fractions.

This lesson is designed to help students generate rules for comparing fractions. The students will use fraction tiles to discover ways to compare fractions with the same denominator or fractions with the same numerator. They will also begin to use benchmark fractions to help make comparisons and complete inequalities.

Would you rather have 2/4 or 6/12 of a Hershey Chocolate Bar? The students will create a fraction tool kit from construction paper to investigate equivalent fractions using rectangular area models.

Students explore how they can compare fractions by considering the denominator. Students use real world examples to create models and demonstrate that the size of the piece decreases as the denominator increases.

In this lesson, students will examine real-world recipes and determine if the fractions are less than one or greater than one. Fractions and ingredients are recorded on a chart within the groups. Games are mixed in to make learning interactive and engaging.

In this lesson, students will demonstrate their understanding of comparing fractions with the same denominator through engaging problem solving. Students will plot fractions on a numberline, play fraction war and complete a worksheet.

Students will demonstrate their understanding of comparing fractions with the same numerator through engaging problem solving using real-world application with brownies as a model. Students will be actively engaged in a fraction war game and "would you rather have" statements to solidify their understanding of comparing fractions with the same numerator.

In this lesson, students will place fractions on a number line and identify equivalent fractions. Students will explain the definition of equivalent fractions.

In this lesson, students will use fold papers to create models to represent equivalent fractions. They will be able to identify representations of equivalence.

In this lesson, 3rd grade students will compare fractions which have the same numerator and explain their reasoning. The students will be able to compare the fractions by correctly placing them on a number line.

Students will identify equivalent fractions to 1/2 using manipulatives and determine what happened to the numerator and denominator when an equivalent fraction was formed.  They will practice this idea by identifying equivalent fractions in a domino game.

In this lesson, students will use Cuisenaire rods to measure lengths and generate equivalent fractions. This is a concrete way to introduce how to generate equivalent fractions by finding patterns in the numerators and denominators.

In this food-themed lesson students work to understand why fraction comparisons must refer to the same whole to be valid. This lesson covers part "d" of standard MAFS.3.N.F.1.3. (In this standard there are parts a, b,and c.)

In this MEA, students will have the opportunity to apply what they learned about physical properties to a realistic problem. Students will be asked to develop a varied diet for a chimpanzee at the CPALMS Rehabilitation and Conservation Center based on the color, shape, texture, and hardness of the food. In the optional twist, students will need to modify their original diet for a senior chimpanzee. 

This is a lesson in the Grade 3 Physical Science Unit on Properties. This is a themed unit of SaM-1's adventures at the CPALMS Rehabilitation and Conservation Center.  To see all the lessons in the unit please visit https://www.cpalms.org/page818.aspx .

In this video, SaM-1 introduces a part 2 twist to the Model Eliciting Activity (MEA). In the optional twist, students will need to modify their original diet for a senior chimpanzee. The first video provided meal planning information to add to the knowledge students gained throughout the unit to start the challenge.

In the optional twist, students will need to modify their original diet for a senior chimpanzee. The optional twist also has a SaM-1 video to introduce the twist challenge.

Learn how different-sized fractional parts can represent the same amount of a whole, different-sized fractional parts in different orientations can represent the same amount of a whole, and a number line can be used to represent fractional parts of a whole in this interactive tutorial.

This task is meant to address a common error that students make, namely, that they represent fractions with different wholes when they need to compare them. This task is meant to generate classroom discussion related to comparing fractions.

The purpose of this task is for students to compare fractions using common numerators and common denominators and to recognize equivalent fractions.

The purpose of this task is to present students with a context where they need to explain why two simple fractions are equivalent and is most appropriate for instruction.

The purpose of this task is to extend students' understanding of fraction comparison and is intended for an instructional setting.

In this activity, students highlight portions of circles or squares that are equivalent to a given fraction. As the student highlights sections, a pointer on a number line between zero and one updates so they can see when they are close or equal to the given fraction. This activity allows students to explore equivalent fractions by making it necessary that each of the three fractions have a different denominator but have the fractions be equal. This activity includes supplemental materials, including background information about the topics covered, a description of how to use the application, and exploration questions for use with the java applet.

Students can practice answering mathematics questions on a variety of topics. With an account, students can save their work and send it to their teacher when complete.

By making popcorn together with your child you may also introduce the concept of fractions.

In this Khan Academy video four fractions are compared by plotting them on a number line and drawing models.

Use fraction models and a number line to represent 1 as a fraction.

This virtual manipulative will help the students to build fractions from shapes and numbers to earn stars in this fraction lab. To challenge the children there are multiple levels, where they can earn lots of stars.
Some of the sample learning goals can be:

• Build equivalent fractions using numbers and pictures.
• Compare fractions using numbers and patterns
• Recognize equivalent simplified and unsimplified fractions

Match shapes and numbers to earn stars in this fractions game.

• Match fractions using numbers and pictures
• make the same fractions using different numbers
• Match fractions in different picture patterns
• Compare fractions using numbers and patterns

This virtual manipulative allows individual students to work with fraction relationships. (There is also a link to a two-player version.)

An interactive tool to represent a fraction circle, rectangle, or set model with numerators and denominators ranging from 1 to 100. The decimal and percent equivalents of the created fraction are also displayed.
