The use of the kindergarten gifts
The use of the kindergarten gifts is a 1918 manual by Grace Fulmer, published in Boston by Houghton Mifflin, for kindergarten teachers working with the Froebel building blocks. Its pictures are line drawings of wooden block constructions shown in isometric projection, numbered like a catalogue of assembled forms, which a designer could take as a model for modular geometric structures and stacked block arrangements.
