What Is the LEGO Education Computer Science & AI Kit? A Coach's First Look

The LEGO Education Computer Science & AI kit is LEGO Education's new hands-on classroom system for teaching coding and artificial intelligence to kids in grades K–8. Each kit pairs LEGO bricks with motors, a color sensor and a free coding app, and it's built for a group of four students. Kids learn real computer science ideas (loops, conditionals, variables, functions) and basic AI ideas (how a computer learns to classify things from data) by building models that move and react. We already use it in our weekend classes at Fusion Robotics Education, so here's our coach's-eye view.

Three kits, three grade bands

LEGO Education sells the system as three separate kits, one per grade band:

  • K–2 (set 45520): the youngest kit, focused on inputs and outputs, events, sequences and loops. It was scheduled to start shipping in the US in September 2026.

  • Grades 3–5 (set 45521): 321 LEGO bricks, a double motor, a color sensor and a connection card. Adds conditionals and variables.

  • Grades 6–8 (set 45522): 379 bricks, a double motor plus a single motor, a color sensor and a controller. Adds functions and a Python option for advanced learners.

Every band also includes AI and data lessons, so a second grader and an eighth grader both meet machine learning, just at different depths. Lessons are written for 45-minute class periods and come with free teacher materials in LEGO Education's Teacher Portal.

How kids code it

The main software is the LEGO Education Coding Canvas, a block-based app that runs in a web browser or on an iPad. Younger kids can use icon blocks, older kids use word blocks, and students in grades 6–8 can move on to text-based Python that runs on their own computer.

Two details stood out to us as coaches:

  • No student logins. Work is saved on the device, and once the app is installed for offline use, it doesn't need the internet.

  • LEGO Education says AI models are trained and run locally on the classroom device, so student data isn't sent to LEGO or anyone else. That makes it much easier for schools and families to say yes.

What the AI part actually teaches

This kit doesn't build a chatbot. LEGO Education treats AI as part of computer science: kids collect examples, train a simple model to sort them into groups, then test it and notice when it gets things wrong. Along the way they talk about data quality, probability and bias, and why a model is only as good as the examples it learned from.

We like that framing. It turns AI from something mysterious into something kids can poke at, question and improve, which is exactly the habit we want them to carry into a world full of AI tools. If your child wants more on this, our AI course covers the same ideas at their own pace.

Our first impressions as coaches

  • Quick wins. Builds come together fast, so kids get to the coding and testing part of a lesson sooner.

  • Real CS vocabulary. The lessons name the concepts (loops, conditionals, variables, functions), which makes the jump to Python or Arduino later feel natural.

  • Made for teamwork. One kit per four students works well in a classroom. At home, one child gets the whole kit to themselves.

  • Classroom-first. It's sold through LEGO Education rather than toy stores, and the lessons assume a teacher is guiding the group.

Where it fits with SPIKE and LEGO League

LEGO Education retired SPIKE on June 30, 2026, and the Computer Science & AI kits are its new direction. They're also the kits for LEGO Education's own LEGO League (ages 5–16), which launches in August 2027 after the 2026–27 BIOGLOW season ends as the final FIRST LEGO League season. SPIKE will still be allowed in LEGO League for 2027–28. If you're weighing that decision, read our guide to LEGO League vs FIRST's new K–8 program.

Common questions

Can I buy the LEGO Computer Science & AI kit for home?

It's sold through LEGO Education's website as a classroom product, built for four students. A family can buy one, but most kids will get more from it in a guided class. If you want a home kit, our kit guide lists coach-tested options.

Does my child need to know how to code first?

No. The K–2 and 3–5 kits start with block coding and no prior experience. Older students can grow into Python. A free start like our Scratch course is a nice warm-up, but it isn't required.

Is there an online course for this kit?

Not yet. We teach with the kit in our in-person classes now, and an online Fusion Robotics Education course for it is coming soon. Until then, our LEGO SPIKE Essential course (grades 1–5) teaches the same building-and-coding habits.
