http://www.superkids.com/aweb/tools/(We used this site to generate basic math worksheets. It offers some slightly different changeable parameters than mathcafe.com. It also has a few games and vocabularies for SAT that we have not used yet.)
http://www.mathplayground.com/(This is a cute website with lots of math games.)
http://www.softschools.com/(We originally found this website to generate simple word problems and realized that it offers games in other subjects such as science and social studies.)
Enjoy!
