The CUBELETS Computational Thinking Expansion Pack from Modular Robotics is a curriculum-focused add-on for classrooms, camps, and clubs that already run Cubelets. Rather than coding on a screen, students snap magnetic robot blocks together and watch behavior emerge from how the pieces connect. The pack layers a structured Computational Thinking unit on top of your existing hardware, walking learners through pre-programming concepts such as values, inputs and outputs, conditionals, events, and sequences — the building blocks of algorithmic reasoning, decomposition, pattern recognition, and abstraction.
Each Cubelet is its own tiny robot with a computer inside; SENSE blocks read the environment, THINK blocks process information, and ACT blocks turn it into motion, light, or sound. Combine them and the robot's behavior is the sum of how the blocks talk to their neighbors. That tangible, wires-and-syntax-free model makes abstract programming ideas concrete for hands as young as Pre-K while still scaling to high-school activities. The expansion adds robot blocks, brick adapters, storage, and a 5-port battery charger to extend an existing collection, plus the lesson library that drives the unit.
RobotLAB resells the Computational Thinking Expansion Pack at $235 and supports schools and programs nationwide with sourcing, deployment guidance, and educator onboarding. Note that this is an expansion, not a standalone classroom set — it is designed for a class, camp, or club that already owns Cubelets Six kits, Cubelets Twenty kits, or an Educator Pack. If you are starting from zero, RobotLAB can pair this curriculum pack with a base kit so you have both the hardware and the lessons in one order.
