Our rookie team had a blast participating in the tournaments.  In the 2 months leading to the competition, they developed great interest in Mindstorms programming and problem solving.  I thought it will be a waste if they do little with their new-found enthusiasm until next September.  Would appreciate any suggestions from the seasoned teams on what activities you've tried that can maintain or even increase 4th/5th graders' interest throughout the year.

Many thanks!
