Assembled for eager inventors, the Brilliant Builder Pack includes 19 SENSE, THINK, and ACT Cubelets®, as well as the Bluetooth® Hat. Designed to support a single student group, this Pack gives students tons of building options as they complete challenge after challenge.

Cubelets make the principles of programming easy to learn and practice. Inside of each block is a part of a program – as you build your robot you build the code that controls its behavior. It’s hands-on coding!

Each Cubelet has a special function and belongs to one of three categories: SENSE Cubelets take in information from the robot’s environment. THINK Cubelets compute and change that information, and ACT Cubelets turn that information into physical action.

Connect at least one SENSE, THINK, and ACT Cubelet to create a robot construction.

Cubelets’ magnetic faces make them simple to snap together and pull apart. Each Cubelet has a special function. What you connect, and how you connect them changes the behavior of your robot constructions. Every combination is a new creation.

Every Cubelets set and pack includes access to free standards-aligned lesson plans, printable activity cards, online professional development, and more.

Block by block, robot by robot, Cubelets help develop vital skills.
