What is FIRST® LEGO® League Jr.?

It's never too early to discover STEM. FIRST LEGO League Jr. is designed to introduce STEM concepts to kids ages 6 to 10 while exciting them through a brand they know and love − LEGO®.

Guided by two or more adult Coaches, teams (up to 6 members, grades K-4) explore a real-world scientific problem such as food safety, recycling, energy, 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 Jr. Core Values, which include respect, sharing, and critical thinking. At the close of each season, teams come together on a regional basis to share their Show Me poster and model, celebrate, and have fun!

Creature Craze

FIRST® LEGO® League Jr. Challenge

Each year, FIRST LEGO League Jr. presents a new and exciting Challenge to ignite the creativity of children age 6 to 10 and introduce them to the excitement of STEM and learn the skills linked to the engineering design process.


In the 2016-17 CREATURE CRAZESM Challenge, teams around the globe were asked to:


  • Choose an animal that lives within the same habitat as a honey bee, using their Inspire Set for inspiration.
  • Learn about the animal and its habitat.


  • Build a LEGO® model that shows their selected animal and the honey bee (using their Inspire Set). The model helps the team show what they learned about their animal. They learn basic programming and design skills using LEGO Education WeDo to make their model move. 
  • Create a Show Me poster to teach others about their team and what they learned.



  • Share what they have learned by participating in an Expo. They could also opt to hold an open team meeting and present their LEGO model and Show Me poster to family and friends.
  • Share their work in the FIRST LEGO League Jr. Online Showcase at flljrshowcase.firstinspires.org
