Oh No Fractions!

on no fractrions

Updated again! This app keeps getting better and better because the developer encourages teacher input. How wonderful is that –  a developer willing to listen to teachers’ needs!

Oh No Fractions! is a great FREE iPhone/iPad app for comparing and exploring fractions. The app is simple to use – kids just swipe to the right or the left to indicate whether one fraction is “greater than” or “less than” or “equal to” a second fraction. As they work, kids can tap above each fraction to see if it can be reduced/simplified – a great feature. But, one of the best features of this app is the “peek”/”prove it” feature. Kids can use a manipulative to “peek” at an answer before they commit to it or they can use the manipulative to “prove” their answer later. This feature is fabulous because it allows the child to visualize his/her answer. Kids can also use this app to practice finding the common denominator. Then they can use it for addition, subtraction, multiplication, and division of fractions. The app also generates corresponding decimals/percentages for each answer. What a great tool for helping kids to understand fractions!! It’s no wonder that it received the 2013 Children’s Technology Review Editor’s Choice Award.
