Wow! What an excellent site! Thank you!
I downloaded this small math program for Joshua and found it drills Matthew as well on his multiplication and division. It can be made as hard or as easy as you like...Joshua is doing the 4+3= type problems...
It's shareware, but I can't figure out how to register it! And it just says "unregistered" and works just fine.
