FLL stands for first First Lego League. So it's FLL for short. The FLL site says -
"The best way to summarize FIRST LEGO League is to say that it is a robotics program for 9 to 16 year olds (9 to 14 in the US and Canada), which is designed to get children excited about science and technology -- and teach them valuable employment and life skills. FLL can be used in a classroom setting but is not solely designed for this purpose. Teams, comprised of up to ten children with at least one adult coach, can also be associated with a pre-existing club or organization, homeschooled, or just be a group of friends who wish to do something awesome."-FLL
But if you still wondering what that has to do with Legos, we build Lego robots that compete in challenges!
