IEAR.ORG: "This app is fantastic!! It takes the students through the steps of a long division problem and shows them how each step of the problem is related to multiplication."

COMMON SENSE MEDIA: [with the Visual Fractions Decimals and Percentages app] "Kids can learn about values and conversions among fractions, decimals, and percentages. These are often difficult concepts for kids to grasp, but they are a primary focus of many Common Core math standards. Creating models is an excellent way to help kids visualize parts of a whole, and they will likely be doing this often in the classroom and during formal assessments. By using this tool, kids can divide the models into as many as 10,000 units on grids and as many as 360 units on circles. Kids can also represent mixed numbers using multiple whole grids or circles. These many options allow for kids of varying abilities to use the tool."

Endorsed by press

EDUDEMIC included the iDevBooks series of math apps in their list of the 20 best education apps and web tools of the year 2012: "These apps get three thumbs up from Edudemic because they’re so easy to use, and focused on making the concepts easy to learn rather than being bogged down with bells, whistles, and ads."

WIRED.COM: "Depending on your needs, you may not need all of these apps, but each one serves to teach and allow practice in a targeted area. The more ways you play with numbers and manipulate the methods to get to the correct answer, the more you understand how it all works. For anyone having trouble with arithmetic, these apps are an excellent choice for practicing and learning new methods."

New app: Fraction as Slope

The Fraction as Slope app provides algebra students a new visual way to think about slope and fractions by showing how fractions are slopes. This provides an opportunity to increase conceptual understanding of both fractions and slopes.

Teachers with Apps: "This a very elegant app in its simplicity of design and the ability for kids to practice math skills independently. It keeps kids on target for tasks that often are laborious by allowing them a choice in how they are to proceed. It implies that there is trust and confidence in a child’s abilities to learn and be independent. And sometimes that is all a child needs is someone believing they CAN. "
