FIRST® LEGO® League Jr. is an exciting Science, Technology, Engineering and Maths (STEM) programme for 6-9 year olds. Each year a theme relevant to the world around them is chosen as a focus for the children’s work. The teams research the topic, displaying their ideas on a Show Me poster, build a LEGO® model and program one part to move using LEGO Education WeDo 2.0. FIRST® LEGO® League Jr. rapidly develops teamwork, design, programming and communication skills, but the most important thing is that it is great fun and makes the children feel proud of what they have achieved!

How FIRST® LEGO® League Jr. works

  1. Form a team of up to six children, ages 6 to 9. You can form this team however you like: through a school, as a family, with a community group or in any other way.
  2. Choose an Expo and register to take part (see below). It costs £40 (including VAT) per team. You'll then be sent a Team Meeting Guide for the coach. This guide suggests step by step instructions of how you can organise the team’s activities. You will also receive a LEGO "Inspire Set", which contains the Inspire Model and lots of bags of extra LEGO® and an Engineering Notebook for each team member.
  3. Purchase a LEGO Education WeDo 2.0 set. These are available from any LEGO Education distribution partner. Or through our Official Mindstorms/WeDo 2.0 partner Raising Robots.
  4. A new Challenge is set worldwide each year and you need to download the Challenge document to get started.
  5. Coach your team as they work on this Challenge over several weeks
  6. Bring your team to the nearest “Expo” event where they'll present their work to other teams and adults.

You don't need any particular expertise to be a team coach - just an enthusiasm to help the children develop life skills while investigating a STEM topic.

Each year, FIRST® LEGO® League Jr. presents a new and exciting Challenge to ignite the creativity of young children. While exploring the real-world theme, teams will learn about simple machines as they build a model made of LEGO® elements with a motorised part. They will also learn to present information through a Show Me Poster. Throughout their experience, teams will operate under a signature set of Core Values, celebrating discovery, teamwork, and Gracious Professionalism®.

What is FIRST LEGO League Jr (video):


“Students see it as a club, but we look at it as an extension of the school day, because it teaches fundamental science concepts, it encourages teamwork, and builds social skills.”
