In the spring of 1971, an initial version of a program to teach selected prereading skills was tried out in three kindergartens. The three visual skills to be taught by the program were attending to letter order, letter orientation, and word detail. The sound skills to be taught were sound matching and sound blending. The program materials for children consisted of whole group, small group, and individual games and activities designed to teach the selected skills. The teacher was provided with a manual describing the games and the suggested scheduling, grouping, and assessment procedures. This working paper summarizes the conditions of the tryout; describes and evaluates the program components in detail, and suggests revisions for the 1971-72 full-year testing of the program.
