Every KEVA piece is the same, approximately 1/4 inch thick, 3/4 inch wide and 4 1/2 inches long. You build structures by simply stacking the planks. No glue, no connectors. They can be stacked upright which looks like it would be unstable as a house of cards, but even this type of structure is surprisingly stable. The simplicity is compelling. Just as it is hard to explain why something is funny, it is hard to explain why most people become captivated by KEVA Planks.
KEVA Planks introduce children to problem solving and abstract thinking, and foundational concepts of mathematics, physics, and design. Young children develop coordination, spatial awareness, and fine motor skills when they reach, pick up, stack, or fit blocks together; they build strength in their fingers and hands, and increase eye-hand coordination. As they get older children begin to figure out which shapes will fit where, and get a head start on observing, comparing, estimating, planning, and making decisions. The planks offer an opportunity for counting, adding, and ultimately understanding more abstract concepts such as gravity and dimension. They build language skills as children describe shapes, sizes, and their ideas. And they foster cooperation, collaboration, and friendship. For older children, engineering, architectural, and artistic experiments result in towers, bridges, sculptures, and contraptions.
