Edge is a leveled core reading/language arts program designed for striving readers and ESL students in grades 9-12. Edge is designed to help prepare all students for college and career success with dynamic National Geographic content and authentic and multicultural literature. Edge was built around relevant and motivating content, preparation for success on the new CCSS tests, and systematic and focused teaching materials, all while incorporating and covering the Common Core State Standards. The reading selections in Edge were specifically chosen to engage adolescent striving readers, get students excited about reading, and create a context for discussion and learning. Program authors Alfred Tatum, Michael Smith, and David Moore have conducted decades of research on how to select literature that engages and inspires adolescent striving readers as well as incorporate best, research-based teaching practices to ensure success for all students, increase reading and comprehension levels, and prepare students for success beyond the high school classroom.
