Hi there, Prezi is an amazing tool! I used it for a presentation on TD specifications to my HOD and he was very impressed with it! So far, I have not had the time to incorporate it into my lessons, as it takes quite a while to prepare and.... I've noticed that it's a bit of a challenge to write on top of it when teaching (or bringing the children up to the front to write on it...etc) - however if you figure out a way of doing this, please let me know! All the best and sorry I wasn't much help.
