I'm looking for an old educational game.?

I remember when i was in like middle school, There was this game that the whole cl would play and it was a huge game with puzzles and it had (in my opinion)(And What I remember) The coolest storyline EVER for an educational game. I think it was a huge series of games. I can't really recall much more then that. I also want to ask, What Math Blasters game did you have a band and you traveled around in a van. You would stop for gas and do math. Then you would get to a gig and the better you do in math the better you rocked out. It was cool. Thanks everyone....
