UPDATED and even better!! 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 new feature) a second fraction. 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.  The “peek”/”prove it” feature of this app is fabulous because it allows the child to visualize his/her answer.

Kids can also practice finding the common denominator then use the app for addition, subtraction, multiplication and division of fractions. The app then generates the corresponding decimal and percentage for the answer. The developer made several improvements to this already great app after receiving feedback from teachers –  how wonderful to have a developer willing to listen to teachers’ needs!

Great tool for helping kids to understand fractions!! Recommended!
