This Fluency Practice is a part of the Lesson 10, Unit 3, Grade 6. Photocopy the attached two-page Sprints so that each student receives a copy. Time students, allowing one minute to complete Side A. Before students begin, inform them that they may not skip over questions and that they must move in order. 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.
