Here's a good interactive site students could use to practice addition and multipication. The games all follow the same format...add or multiply and type the answer, however students may practice leveled problems. Lower grades may use the easy while upper grades go to the more difficult. Make sure you try this out first to make sure you have anything you need on your computer to run this program. Thanks to the blog, iLearn Technology.
