My son loves Times Attack. It has really been a blessing getting him to work on multiplication tables. He is in second grade and has almost mastered the 9's! Here's the website to download a FREE copy www.BigBrainz.com.
My Comments: We have used this program too. Boys seem to like it a little more than girls. If your children don't watch much TV you might want to view it first. The theme has an ogre and they walk around in a dungeon and answer times facts to open certain doors. It might be a little spooky for some children.
