Oklahoma Ag in the Classroom is a program of the Oklahoma Department of Agriculture and the Cooperative Extension Service that aims at providing educators with opportunities to help youth understand the importance of agriculture in everyday life. This book includes a collection of ready-to-use teacher guides and activity sheets that can be used to integrate agriculture into school subjects in such a way that students become "ag-literate" while learning language arts, reading, information skills, mathematics, science, social studies, and visual arts. The lessons in this book, targeted at grades 3-4, are designed to supplement existing curricula and are arranged by subject matter area. Lessons are arranged by level of difficulty within each subject area. Teacher guides include the following: subject, agricultural topic, student skill, learner objective, grade, concept, step-by-step instructions, background, resources, evaluation, and related activities. A glossary, pattern pages, suggestions for requesting assistance, writing pages, and resource lists are included. (JRH)
