This Fluency Practice is a part of the Lesson 8, Unit 2, Grade 7. Before students begin, inform them that they may not skip over questions and that they must move in order. Time students, allowing one minute to complete Side A. After one minute, discuss the answers. Before administering Side B, elicit strategies from those students who were able to accurately complete many problems on Side A. Administer Side B in the same fashion, and review the answers.
