Play Time - The Playtime Unit of the How and Why Program of Child Mental Development

L. J. Bullard Co, 1949. A 10.5" by 7.5" box style folio with 37 Play Time booklets. The reverse of the box indicates the series was designed for young children to learn by doing - nursery through primary grades. This is followed by contributors and artists and a list of available Play Time books. Apparently only a portion of the list is in each box and in no particular order. The booklets range from 4 to 8 pages and encourage learning in many different ways, from cutting and dressing paper dolls, to counting and drawing, reading, cooking, creating shadow puppets and much more. There is a reference to an "Instant Guide to How and Why Program" which is not present. Partially completed by a child.
