If you are looking for more ways to introduce fractions to your child and give them visual representation, this could be a great app to check out.
The app is pretty simple. The player simply moves 2 dials - a numerator and a enumerator, to change a fraction that is shown on a pie illustration, giving the visual representation. The dials allow for numbers 1-12 to be included in the pie. It does not allow for the numerator to be larger than the denominator. Again, for beginners. Definitions are included.
Hope you might find this useful. If not, the download was free!
Compatible with iPad.
