Intended as a supplement to the social studies program in the kindergarten through the second grade, this bulletin suggests teaching materials and activities in Puerto Rican studies to provide young children with knowledge of the history, customs, values, and contributions of the Puerto Rican people. The introduction contains objectives for pupils and teachers, a scope and sequence outlines, and suggestions on the use of informal learning centers and use of bulletins. The learning activities are presented by grade level and according to themes related to the social studies program (home and school environment, kindergarten; the local community, grade 1; and communities around the world, grade 2). Activities are listed in a columnar fashion, correlating teacher actions to pupil behavior. A bibliography includes books for children, references for teachers, records, study prints, and filmstrips.
