This guide presents lesson plans, with handouts, biographical sketches, and teaching guides, which show ways of integrating African American role models into mathematics and science lessons in kindergarten through grade 6. The guide is divided into mathematics and science sections, which each are subdivided into groupings: kindergarten through grade 2, grades 3 and 4, and grades 5 and 6. Many of the lessons can be adjusted for other grade levels. Each lesson has the following nine components: (1) concept statement; (2) instructional objectives; (3) male and female African American role models; (4) affective factors; (5) materials; (6) vocabulary; (7) teaching procedures; (8) follow-up activities; and (9) resources. The lesson plans are designed to supplement teacher-designed and textbook lessons, encourage teachers to integrate black history in their classrooms, assist students in developing an appreciation for the cultural heritage of others, elevate black students' self-esteem by presenting positive role models, and address affective factors that contribute to the achievement of blacks and other minority students in mathematics and science. Affective factors include developing positive attitudes in the early and middle grades, developing the ability to persist in the face of barriers, addressing stereotyping in mathematics and the sciences, understanding the utility of achievement in mathematics and science for everyday life and future careers, and maximizing the teacher's role as a positive significant other for the student. Three appendixes provide a summary of factors influencing minority student participation in mathematics and science, bibliographies of African and African American contributions to mathematics and science, and resources for incorporating African American role models in mathematics and science.
