Before I was blessed with a pod of ipads, I embraced my pod of "slow going" desk tops. We now have just 1 slow going desk top in our classroom. We still use all kinds of great sites during our lab time and I post them on our class wiki for the kids to explore at home. Check out this great link to awesome Halloween games on line. (It is one of my most favorite tech blogs)
And here are a few Halloween apps (just for fun)........
Abbey Halloween Math - free
Halloween counting and words - free
