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” the other. After the child answers, there is an opportunity to “prove it” – see above picture. The “prove it” section of the app is fabulous because it allows the child to visualize his/her answer. I would love to see the developer add an “equal to” option to this app to make it even better!
