This Fluency Practice is a part of the Lesson 16, Unit 2, Grade 7. Before beginning, inform students that they may not skip over questions and that they must move in order. Allow students one minute to complete Side A. After one minute, discuss the answers. Before moving on to 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.
