3 FIRST LEGO League Divisions

FIRST LEGO League guides youth through STEM learning and exploration at an early age. From Discover, to Explore and then to Challenge, students will understand the basics of STEM and apply their skills in an exciting competition while gaining productive learning habits, confidence, and teamwork skills along the way.


For children ages 4-6, Discover is a playful introductory STEM program that ignites natural curiosity and builds habits of learning with hands-on activities in the classroom and at home using LEGO® DUPLO® bricks.

GRADES 2 – 4

In Explore, teams of students ages 6-10 focus on the fundamentals of engineering as they explore real-world problems, learn to design, and code and create unique solutions made with LEGO bricks and powered by LEGO® Education SPIKETM Essential or WeDo 2.0.

GRADES 4 – 8

Friendly competition is at the heart of Challenge, as teams of students ages 9-16* engage in research, problem-solving, coding, and engineering – building and programming a LEGO robot that navigates the missions of a robot game.

It’s never too early to discover STEM. FIRST LEGO League Explore introduces science, technology, engineering and math (STEM) concepts to kids ages 6 to 10 while exciting them through a brand they know and love − LEGO®.

Guided by adult Coaches, teams of up to 6 members explore a real-world scientific problem such as energy, transportation of goods, recycling, etc. Then they create a Show-Me poster that illustrates their journey of discovery and introduces their team.

They also construct a motorized model of what they learned using LEGO elements. In the process, teams learn about teamwork, the wonders of science and technology, and the FIRST LEGO League Explore Core Values and  critical thinking. At the end of team season they come together at a Festival to show what they’ve learned, share ideas, celebrate, and have fun!

FIRST LEGO League Expolore teams get to:

  • Design and build challenge solutions using LEGO® elements and motorized parts
  • Apply real-world math and science concepts
  • Research challenges facing their community today
  • Learn team-building and presentation skills
  • Develop Show-Me posters to present their research journey
  • Learn to work together and accept others opinions
  • Share ideas and talents
  • Build self-confidence, knowledge and life skills
