Flash movie with interaction and quiz. Drag and drop operation to promote awareness of equivalent fractions and the idea of a common denominator. Useful for whole class (with digi projection and IWB useful) and one to one and small groups around the PC.
Feedback appreciated and particularly if you spot errors/bugs.

NOTE – recent changes to flash readers has caused a little problem. When you download the activity you’ll see a BLACK screen. Don’t worry. Just RIGHT CLICK and select PLAY and it should run.
Sorry for the inconvenience. Ed

If you find it useful give it the THUMBS UP. In either case add a comment below … no offense taken … feedback is IMPORTANT. It may help the evolution of learning activities. Ed
