As an aside I mentioned this to my (primary school) teacher friend.
For what it's worth I pass on her remarks:
What they do is to use clementines (small easy peel oranges). These
neatly segment into halves quarters and so on, apparently the
difficulty is getting the "numberness" of fractions over and this is a
good way of illustrating it visually. You can see a quarter [1/4] and
three quarters [3/4] etc.. Apparently once this concept has been
grasped fractions are then easy. A further benefit for her pupils
anyway is that you can then eat your work.....
