Cubelets are modular robot blocks that snap together magnetically to create working robots. Each cube has a specific function—such as sensing, thinking, or acting—and when combined, they form a complete robotic system. Students can build robots without coding at first, then extend learning through block-based programming. Cubelets make robotics hands-on, intuitive, and accessible for all learners.

Encourage creativity through open-ended building
Support collaboration and teamwork
Introduce coding concepts through hands-on exploration
Build understanding of cause-and-effect relationships
How to Use This Tool
How to Use This Tool
Introduce students to the different Cubelets (Sense, Think, Act)
Demonstrate how cubes snap together magnetically
Have students build a simple robot (battery + sense + action)
Let students test and observe how the robot behaves
Challenge students to change one cube and observe differences
Introduce specific tasks or challenges (move, light up, react)
Extend learning using Cubelets Blockly for coding (optional)
Classroom Ideas

Create a robot that represents a character trait
Use vocabulary like “predict,” “observe,” and “explain” during builds
Math
Math
Explore patterns by rearranging cubes
Practice sequencing and order
Use cause-and-effect to support logical thinking
Measure distance or speed of robot movement
Identify patterns in robot behavior
Introduce early algebraic thinking (if this changes, then that happens)
SCience
SCience

Helpful Tips
Helpful Tips
Start with just 3 cubes (Sense + Think + Act)
Let students explore before giving directions
Ask “What do you notice?” and “What changed?”
Encourage trial and error—there is no “wrong” build
Use small groups to maximize engagement
Rotate roles (builder, tester, observer)
Introduce coding only after hands-on exploration
