## Introducing Fractions, a New App from MLC

Cynthia Hockman-Chupp

We’re proud to announce the release of our newest free math app, Fractions for iPad, Web and Chrome! With this app, students can use a bar or circle to represent, compare, and perform operations with fractions with denominators from 1 to 100. They can choose the fraction model and number of equal parts or use a color to select specific parts to show a fraction of the whole.

What’s especially cool is that the Fractions app creates opportunities to investigate and compare fractions. If, for example, the white bar has a value of 1, what might be the value of the colored bars that follow?

Students can check and justify their predictions by coloring in or counting the remaining sections in each line. As they identify the value of the pieces relative to the white strip, the fractions can be labeled.

One idea is to ask students to pair-share any mathematical observations they can make about the pieces and invite volunteers to share their thinking. Be sure to note along with them that each row of fraction pieces is equivalent to 1. Then work with students’ input to write a set of equations representing these equivalencies on the board. Have students build and report equivalencies for ½, ¼, and ¾ as you record equations to match.

If they have access to the app, students can continue the exploration by building their own representation of the following fractions, sharing observations with each another and the class as they work.

3/16, example:

5/8

3/4

5/16

7/16

Can they then record equations that result in the sum shown on the model?

Enjoy the new Fractions app! And let us know on Twitter how you’re using it in the classroom by tagging @MLCmath or using #BridgesMath !

The free Fractions app is available to use as a web app or can be downloaded from iTunes or the Chrome Web Store. Download Fractions and learn more here . For step-by-step instructions for using Fractions, check out the info button from inside the app.
