planks

KEVA Planks are cuboid wooden block toys for children and adults. Each block is sized approximately 1/4 inch (6.35 mm) x 3/4 inch (19.05 mm) x 4 1/2 inches (114.3 mm). The blocks are available for sale in maple, that is produced in the United States, and less expensive imported pine versions.KEVA Planks started out as a simple construction set that is unusual because they only use one piece and no connectors in glue, in contrast to other building sets that often have specific instructions and require sorting. It has developed into a teaching tool used in classrooms and enjoyed in homes.
A number of museums have KEVA exhibits for hands on experience with design and construction including:
