Hi, Freddy, FLL bots are pretty cool and the competition missions are good for younger kids because they make connections to help them understand the big picture- how can a robot help solve this problem--MARS, OCEAN SCIENCE, ENERGY... but they are not the only thing you can do... we did a one-day sumo-bot challenge with Mindstorms a few years ago that was a perfect intro with middle school kids.

The VEX has a new preprogrammed bot, Vexplorer, that looks pretty cool, but the program-able bots are better if you want to go farther or deeper into it with your kids. Somebody on our team (Bill Moore!) recently told me that the NXT was programmed to solve a rubiks cube... that seems pretty advanced to me.

When you write your application, Maybe give some thought to how the different ages will work differently...

Good luck!
