Each FLL coach also receives a Coach's Manual. It outlines the goals and usual structure of an FLL team from team size to involvement of the adult or student mentors. One thing the students sometimes need help with is presentation skills and research skills for their research project. As you may know, the research presentation is a big part of FLL competitions as its the first introduction kids have to being aware of their future's problems and also how they can solve them.

Basically what Jon and Rich said are spot on. JFLL and FLL at the same time are also things you can do. Some consider successful JFLL programs to be even more impressive. Imagine having both!
