This app is extremely easy to use and very child-friendly. Basically, a pizza will appear on-screen and children must choose the correct fraction from a choice of three. Once they’ve answered the question, the have to shake the iPad to get a new question.
It’s repetitive, easy-to-understand and completely free.
It is also possible to pay for Pizza Fractions 2 and 3 which operate in the same way but children must pick an equivalent fraction (Pizza Fractions 2) and use the greater than and less than symbols to compare fractions (Pizza Fractions 3.)
