This really belongs under Parents & Teachers heading, for it is primarily a how-to-do-it book for the physical education teacher who needs specific and step by step assistance on methods, progressions, development of routines, safety precautions, etc. in this field of gymnastics. Equipment -- necessary space -- teaching aids, discussed before the presentation of individual stunts and tumbling. With increasing difficulty, successive techniques are presented -- stunts and tumbling with partners of equal size, with partners of unequal size, in groups, and for exhibition. Illustrated by amusing line sketches, and factual photographs.
