If you use PowerPoint in your room, this website has a whole bunch of templates for game show-type reviews. Works great with an interactive white board, too, if you have one.
Asked my Twitter network for ways to help support teaching of long division to third graders, and this is one of the sites recommended. Brought a smile to my face!
Long division was great, I highly recommend the "snork's long division," however multiplication set-up was not the best, 'clicking between answer box and key;' also algebra site needs a little work- try it out.
