FIRST LEGO League (FLL) is an international competition organized by FIRST for elementary and middle school students (ages 9–14 in the United States and Canada, 9–16 elsewhere).
Each year in August, FIRST LEGO League introduces a scientific and real-world challenge for teams to focus and research on. The robotics part of the competition involves designing and programming LEGO Mindstorms robots to complete tasks. The students work out solutions to the various problems they are given and then meet for regional tournaments to share their knowledge, compare ideas, and display their robots.
FIRST LEGO League is a partnership between FIRST and the LEGO Group. It also has a scaled-down robotics program for children ages 6–9 called FIRST Lego League Jr.
