Resources and Tools for Elementary Math Specialists and Teachers

Common Core State Standards for Mathematics

Grade(s) 3 resources related to the following standard:
Number and Operations—Fractions
Develop understanding of fractions as numbers.
3. Explain equivalence of fractions in special cases, and compare fractions by reasoning about their size.
b. Recognize and generate simple equivalent fractions, e.g., 1/2 = 2/4, 4/6 = 2/3). Explain why the fractions are equivalent, e.g., by using a visual fraction model.

This game offers students a chance to practice grouping fractions with the same number value, as well as visual representations of those fractions (using both circles and bars). A "check" button gives students three checks before the solution is revealed, and highlights incorrect groupings with each try. This version of the game is enhanced for interactive whiteboards (IWBs).

In this article Pennant and Woodham discuss the importance of rich tasks in the teaching of fractions. In order to prepare for new more rigorous standards, the authors have compiled a list of rich tasks and a description of others that aim to improve how children think about fractions.

Teachers can use this interactive tool to help students build a conceptual understanding of fractions by creating artwork on a grid, where each color represents a fraction. Students learn how fractions are related to each other and that their value is determined by the value of the unit. This page includes a video demonstration of the tool and sample lessons from the Conceptua curriculum. Free registration is required to use the tool. A paid subscription is necessary to access full curriculum and allow full student use.

This iOS app (free version) has two strategy game activities for children to promote their understanding of fractions and improve their skills. In the first activity the player must drag the correct circular model to its number and in the second activity the player must identify the missing number that makes the two fractions equivalent. Students can play against the computer or another person. In-app feedback also helps students learn why they got answers incorrect.

This collection of lessons, interactive Flash exercises and teacher utilities supports the learning of fraction concepts using side-by-side symbolic and pictorial representations. The lessons cover identifying, comparing, renaming and operating with fractions using circle and number line models. The Fraction Maker feature allows a teacher to create visual models to illustrate those same topics with fractions chosen by the user. The site includes student games and worksheets as well as suggestions and resources for the teacher.

This interactive Flash applet provides students with practice in renaming proper fractions in their lowest terms. Students are shown a fraction and a diagram of it in a unit circle. The student enters the reduced fraction, gets feedback, and when correct is shown a second picture of the equivalent fraction. Instruction in the form of printed and Flash animation examples is provided. This activity is also available in line segment (ribbon) mode from the Rename page.

In this 6-minute video Keith Phelps shows a lesson in which he has his fourth grade students decompose fractions to show one and a half in multiple ways. Students are given a variety of fraction tiles to complete this activity and are asked to build it, draw it, and write a number sentence for their solution. In addition to the video a transcript is provided.

This webpage links to a Java applet that enables students to build fractions, make equivalent fractions, compare fractions, and complete addition and subtraction of simple fractions with like denominators. The applet includes a variety of levels of challenge and representation. The webpage also includes a downloadable applet, a PowerPoint presentation on how to use the simulation, a PDF lesson plan, and a series of eight student recording sheets in PDF format.
