This document is Part II of a two-part project whose object was to identify children's sequential development from birth through age seven and to identify the materials which would be used to strengthen or initiate a behavioral facet. The materials surveyed for potential use with preschool children are described as ranging from standard toys through materials utilized in secondary school systems for educational purposes. The materials are evaluated for application in the developmental sequence. The report is divided into three sections: (1) Material Survey and Application, (2) Manufacturers' Materials Survey, and (3) Materials and Techniques Used in Child Development Centers, Appendixes include (A) Summary of Manufacturers' Reports, (B) List of Manufacturers Supplying Product Data, and (C) Directions for Abstract Card Sorting.
