This toolkit supports the development of an instructional unit on diversity and evolution and aligns with academic standards for science, English language arts, and mathematics for students in grades 9-12. The elements of this toolkit were assembled based upon their suitability for constructing a multi-day instructional unit on hominid evolution that corresponds with the 5E Learning Cycle of engage, explore, explain, elaborate, and evaluate. Your task as a lesson study team is to analyze the materials that are included in this toolkit and evaluate how they can be incorporated in a 5-E instructional unit plan that complies with the academic standards for science, English language arts, and mathematics. As you study these resources it is important to make note of any deficiencies or gaps that will need to be addressed and make modifications in the lesson resources and activities where needed.
