How can a building toy with only two basic pieces be such a great combination of fun and function? The creators set out to make a sturdy, appealing building set that also demonstrates nature's mathematical and scientific principles. Lux Blox are ideal STEM/STEAM products that can be used to demonstrate math principles from counting to geometry, algebra, functions and statistics and science concepts like properties of matter, forces and interaction, and engineering and design. None of this helps if your child won't play with them, but no problem here. The colorful pieces fit snugly together as a rigid triangle, flexible cube, or any number of other geometric shapes and have a natural range of movement up to 240 degrees. Pieces are designed to work with pencils, craft sticks, wires and toothpicks. Unique gear/wheel, axle and rubber band pieces enable the construction of simple machines.
