This booklet is being offered as a resource for Ministries of Education, especially national Curriculum and Textbook Development departments, centres or institutes, and other education providers (as well as interested teachers). It is hoped that ministries will review the topics covered here and consider including them in social studies, language or other subjects, lessons or textbooks, after translation and/ or adaptation to local needs. The examples of possible lesson materials have been developed for upper primary or lower secondary schooling.
