I came across the amazing fact Generator a little while back which has a great collection of both useful and useful facts. The great thing about the amazing fact generator is that regardless of the facts being shared they generally produce a great deal of discussion with my students. Most of the time this leads to getting students to produce some quality writing based on the fact we have just looked at. Hope you like it - Access it here.
