# 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.

##### Features of the Curriculum

- Math Content by Strand
- Standards for Mathematical Practice
- Assessment
- Differentiation
- Review and practice
- Embedded professional development

##### Take a Tour of a Unit (Grade 2, Unit 5)

##### Take a Tour of an E-text (Grade 4, Unit 1)

##### Take a Tour of the Digital Components (Grade 4)
