# The Curriculum

##### Components

Each grade is made up of 8 curriculum units, an Implementation Guide, and a Content Guide. Also available for teachers: a Spanish Companion and an Assessment Sourcebook specific to the grade. Each classroom needs the manipulatives and cards used in that grade, and one Student Activity Book per student. **The curriculum can be taught without access to technology, entirely digitally, or using a blended approach.**
