An outline of physical education for primary and grammar schools, junior high schools, and high schools
A 1917 teacher's manual of physical education by Ernst Hermann, printed in Cambridge, Massachusetts for instructors in American primary, grammar, junior high, and high schools. The plates are overhead floor plans of classrooms and gymnasiums, with pupils drawn as hatched squares topped by circles and half-circles, linked by dashed arrow paths; useful as pictogram crowds, movement diagrams, and repeating grid patterns.
