Many wonderful toys, including Tinker Toys, Erector sets, Kinex, Zometool, and other architectural toys that provide a re-usable construction experience have been developed since Froebel's time. Any of these materials could function as Gift 10 if they are introduced with a Froebelian approach. The idea for all the Froebel Gifts is not to become obsessed with the materials, but with the experiences of the children. If the idea of combining points and lines to form the framework of solids is experienced by the child, the material can rightly be called Gift 10.
