This edition offers three modules at each grade level, with specific offerings at each grade for a total of 18 modules. The edition makes explicit to teachers and students the connections to science and engineering practices, crosscutting concepts, disciplinary core ideas, and Common Core State Standards for English Language Arts and Math.
