The FIRST LEGO League Challenge is an international competition organized by FIRST and created by inventor Dean Kamen for elementary and middle school students. FIRST LEGO League’s three age-appropriate divisions inspire youth to experiment and grow their critical thinking, coding, and design skills through hands-on STEM learning and robotics centered around a yearly theme. Beyond just building a robot, teams also work on an Innovation Project and focus on Core Values and teamwork exercises. A variety of LEGO® products are used in this competition, starting with DUPLO® bricks at the youngest level, then building robots using the LEGO Education WeDo 2.0 system, and finally using the LEGO Mindstorms system for the oldest division.
