KEVA planks are an exceptionally versatile tool for teaching STEAM concepts to children of any age or skill level. Only one simple building block is used which allows for an infinite number of construction possibilities. Planks are assembled using various stacking techniques. Since gravity is the primary force acting on the blocks, compounding variables such as gluing, skill or connector strength are eliminated. Construction progresses quickly so multiple trials or experiments can be conducted in the course of any challenge. Trial and error maximizes discovery.
