Fifty-five Missouri educators have developed a Model Curriculum in social studies, which includes the four major content areas of economics, geography, government, and history--both world and U.S. The major goal behind the units is to give districts models they can use when revising their social studies curriculum. This presentation will explain the process and components to the curriculum. The units are aligned with the Grade-Level and Course-Level Expectations and with the English Language Arts Literacy Standards for social studies. The units are being revised based on feedback from teachers who piloted them. The units can be used in their entirety or parts can be adapted to existing curriculum.
