Spielgaben 5C is a modified version of 5. It has 3” cylinder divided into three concentric rings 1/2″ thick with 3 layers vertically and 3-fold division is maintained in both directions. As with the Spielgaben 8 rings and half-rings, the Spielgaben 5C produces some elegant and beautiful designs.
The Curvilinear Series was developed, like many of original Froebel’s, after Froebel’s death. Froebel had laid the philosophical foundation for these versions in his book Education by Development, but their use was not formalized until much later. Purists have argued against adding to the traditional series, yet Froebel was clearly advocating the use of the curvilinear solids in his writings.
As with the other sets, children will use this Curvilinear Spielgaben 5C to construct both the things they see in their world and the things they imagine: igloos, castles, bridge and the possibilities are endless. Children can divide the Curvilinear cylinder into halves, thirds, and quarters. Geometric concepts such as ring, disc, arc, diameter, radius and concentric can be discovered thorough play. The arcs can be rotated in different directions to prompt discussions of “curving over” and “curving under.” The quarter circle arcs of the Spielgaben 5C can also be used by older children to form letters of the alphabet.
The Spielgaben 5C is more complicated and therefore more suitable for an older child. Like Spielgaben 5, 5C is especially well-suited for creating architectural constructions. Younger children might start with fewer pieces (one layer of 12 pieces) and gradually work up to using the entire set in pattern-making.
