FIRST LEGO League Jr® is a team-based science and engineering program for kids in Kindergarten through 4th-grade. In groups of 2-6 members, guided by 2 adult coach-mentors, teams explore a scientific challenge. They then create a LEGO® model to reflect their ideas on what they have learned. Each LEGO model has a motor and moving part. Models may be programmed using the LEGO WeDo 2.0 or MINDSTORMS® systems. Teams share their experience on a Show Me Poster and at local expos.
