The LEGO® Education Computer Science & AI Kit for Grades 3-5 (45521) is a classroom-ready, standards-aligned solution that builds strong computational thinking in upper-primary students. Learners build motorised LEGO models and bring them to life with the free LEGO Education Coding Canvas – learning events, loops and conditionals, and even creating and training their own AI classifiers.
Each kit is designed for a group of up to 4 students and includes 321 LEGO bricks, a double motor and a colour sensor. Lessons fit within a single class period, and the Teacher Portal gives teachers ready-to-use lesson plans, classroom presentations and facilitation notes – no prior coding or AI experience needed.
What's in the Box
- 321 LEGO® bricks
- Building instructions
- 1 × Double Motor (2 motor outputs)
- 1 × Colour Sensor
- 1 × Connection Card
- 1 × USB charging cable
- Sturdy, stackable storage box
Curriculum – 30 Lessons in 6 Units
Each unit has 4 lessons plus 1 design challenge, with built-in progression. Units include:
- Basics – explore the hardware and Coding Canvas; write pseudocode to break down problems
- Events – actions that cause something to happen
- Loops – repeat sequences of code
- Conditionals – make programs react when conditions are true or false
- AI & Data – use pretrained AI classifiers, then create and train custom AI classifiers (e.g. the "Strike a Pose" lesson)
Safe AI Learning
- Develops students' AI literacy with age-appropriate AI possibilities and challenges
- AI-based computer vision features
- No student login – projects are saved locally and student data is not shared
Devices & Software
Some lessons need one device (laptop, Chromebook or iPad) per group of 4 students to run the free LEGO Education Coding Canvas, available in a web browser or as an iOS/iPadOS app. Several lessons are fully screen-free. Hardware connects wirelessly via Bluetooth Low Energy and charges via USB-C.
Product Highlights
Motorised Builds with Double Motor: 321 LEGO bricks plus a double motor with 2 outputs and a colour sensor let students build moving, reactive models they control with code.
Coding Concepts for Grades 3-5: 30 lessons across 6 units introduce events, loops and conditionals step by step, with a design challenge at the end of every unit.
Create & Train Your Own AI: In the AI & Data unit, students use pretrained AI classifiers and then train custom classifiers using computer vision – an age-appropriate introduction to how AI learns from data.
Built for Classroom Teamwork: Each kit supports up to 4 students, lessons fit a single class period, and the Teacher Portal provides ready lesson plans, presentations and facilitation notes.
Safe & Easy Setup: The free Coding Canvas runs in a web browser or on iPad with word or icon-based block coding, no student logins and projects saved locally; hardware recharges via USB-C.
