Kids build with LEGO, write real code, and explore how AI actually works — not buzzwords, but the real ideas, learned hands-on and from first principles. For grades K–8, in small groups of four.
Save your child's spot →Every session pairs two things kids love: building something real with their hands, and making it come alive with code. Children build working models from LEGO Education kits — the icon-coding SPIKE Essential set (45345) for our youngest, and the SPIKE Prime platform (45678) for older bands — then program what they built to sense, move, and respond.
Coding meets kids exactly where they are. Pre-readers in K–2 program with icon-only blocks — no reading required, just logic they can see and drag. As kids grow, they move to word blocks and then toward real text-based logic: variables, conditions, loops, and debugging. The LEGO always stays in their hands; the code is how they give it a brain.
We will be straight with you, because a lot of programs are not. Across all of grades K–8, kids explore how AI works — what it is, how a machine can "learn" from examples, and where it shows up in daily life. They are not building or training their own AI, and we will never tell you they are.
We follow LEGO Education's official Computer Science & AI curriculum. Through its guided activities, kids see how AI learns from examples and where it can get things wrong — understanding what AI is and what its limits are, without building or training a model of their own.
We don't teach kids to memorize the names of apps. We teach them what's actually happening underneath, so they can reason about anything they meet later. Two ideas anchor the whole program: how a computer makes a decision — step by step, using conditions and loops — and how an AI model learns a pattern from examples instead of being told a rule.
A concrete example: kids look at how a model could tell a red brick from a blue one — and what happens when the light changes and it guesses wrong. They see that a machine only knows what it was shown, in a way no lecture could teach. From there they can reason about far bigger AI systems, because they understand the engine.
