A set of large, hollow, lightweight, seamless, rigid wooden blocks provides a variety of shapes such as cubes, flat or elongated right-parallelepiped pieces, as well as pyramids, and round cylindrical blocks. The pieces are large compared to the size of a child, but being hollow they are not overly heavy. There are no openings in the pieces, so gripping the smooth surfaces to throw them is not a simple task for a small child; thus they are safer since they are more amenable to use on a plane surface and being gripped with both hands. Also, the construction of plywood provides an optimum degree of heft as opposed to large plastic or foam pieces. The size makes the blocks useful either for either single use or group play. The blocks are durable and sanitary.
