The current clarion call in education to prepare students for the 21st century operates as an incentive to rethink elements of the curriculum that will best serve the interests of high-ability learners. "Changing Tomorrow 1" offers instructional activities for high-ability elementary students in grades 4–5 based on the Common Core State Standards that emphasize critical and creative thinking skills and give gifted students an opportunity to apply these skills in an integrative and substantive way. The book includes 10 lessons that address leadership skill development and includes assignments that require students to research and compile biographical information on seven influential men and women drawn from multiple disciplines and diverse backgrounds. Instructional questions, pre- and post assessments, and appropriate rubrics are also included.
