Sense training for children's development in the form of simplified games and exercises
A 1919 teaching manual by Hilda A. Wrightson, published in New York by The McCann Company, setting out sense-training games and exercises for teachers and parents working with young children. The plates are bare line diagrams: a square, circle, or inverted triangle crossed by a few freehand curves that divide it into puzzle-like fields, usable as abstract marks, logo skeletons, or pattern modules.
