Welcome to FIRST LEGO League Jr.!

FIRST LEGO League Jr. is an exciting opportunity for the youngest budding scientists. It encompasses the core concepts of all FIRST programs to inspire, excite, and introduce kids to the wonders of science, technology, and engineering.

  • Teaches the benefits of teamwork
  • Sparks initial interest in science and technology
  • Introduces basic design skills through a hands-on approach with the familiarity and fun of LEGO building
  • Provides a culture of sharing and learning from others

The goal is to provide an experience that will capture young children’s inherent curiosity and creativity and direct it toward discovering the possibilities of improving the world around them through understanding, thought, planning, and technology.

FIRST LEGO League Jr Program Basics

It’s true, children construct new knowledge best when they are constructing something real. The FIRST LEGO League Jr. program does that every year with a new and exciting Challenge to ignite the creativity of children age 6 to 10 . 

Each team of up to 6 children begins the exploration of this real-world theme with an exclusive LEGO® Education Inspire Model. Using this model as a starting point, they design a new model of their own with LEGO® elements. As they work, they learn basic engineering and programming skills with LEGO® Education WeDo and apply those concepts to make their model move. Teams also document their work in an Engineering Notebook and share their journey through a team Show Me Poster.

Throughout their experience, teams operate under the FIRST LEGO League Jr. Core Values, celebrating discovery, teamwork, and Gracious Professionalism®. The season concludes by participating in a super fun, non-competitive official expo which publicly acknowledges and applauds the accomplishments of each team!

How do I get my child on a team?

As a rule, FIRST, including FIRST LEGO League Jr. St Louis, does not place children on teams.
Also, for privacy reasons, we are not able to share lists of team contact information.

Any group can create a team: schools, home schools, community groups, churches, or just some friends who wish to do something awesome. Adults do not need any technical experience to coach a team.

What does it cost?

Cost breakout is by team, not individual child

What is the time commitment?

The FIRST LEGO League Jr. team registration opens in May.

The season challenge details are released in early August.

Official Expos occur on select weekends in February and March (attend only one).

Meeting times vary by team, but generally a team can complete the challenge in 12 facilitated sessions provided in the Team Meeting Guide and Engineering Notebook. New teams may want to hold more meetings to introduce basic engineering and programming sessions. Teams may also include field trips as a part of their challenge research.

What is an Official Expo?

We have fun!
Expos are a non-competitive 2-3 hour event which offer students an amazing experience as they celebrate their hard work, make new friendships, and are exposed to ideas and ideology that will enhance their lives for decades to come.
Our expos begin with teams presenting their challenge research, Show Me board and LEGO model to FIRST LEGO League Jr. reviewers. Presentations wrap up with a short question and answer period.
The all team portion of the expo follows with team building and interactive robot demos from the other FIRST programs. Finally, the event concludes with a super fun, high energy awards and closing ceremony. In FIRST LEGO League Jr., everyone is a winner!
