Pacing Guide = a year-long or course-length schedule for all the units of study within a course. It is not a schedule for learning activities within those units.  

Learning Progressions = "Learning progressions are the sequential building blocks of instruction" or "daily chunks of instruction" (Ainsworth, 2017). 

Buffer Zones = short intervals between units in the pacing guide to allow for remediation and a deeper understanding of priority standards

Length of Units- typically 4 to 6 weeks

Factors impacting the length of the unit:

• age of students

• rigor of content

• assigned priority standards and supporting standards

• planned learning experiences
