powerpoint quizzes are good - get the kids to make up questions and put the answers on the next slide...sets of ? (however many) questions and then test eachother
If you feel up to it you can do it multiple choice and link the answers through with the wrong answers going to a bong slide with a return or try again buton on them....
Activprimary whiteboards also have some quizzy/ gamey stuff in the flash section - but don't know if that's any good to you!
