This mini-app allows you to picture fractions in the form of slices of a circle. As you move the two dials, denominator and numerator, the picture adjusts instantly to show the fraction you have ‘dialled’. It is the ideal way into understanding fractions for beginners. For those already familiar with fractions, further insights can be gained into the effect of changing the numerator or denominator, or into concepts such as equivalent fractions.
