This Fluency Activity is a part of the Lesson 8, Unit 1, Grade 5. Reviewing this skill introduced in Lesson 7 helps students work toward mastery of rounding decimal numbers to different place values. Turn and talk is a strategy intended to broaden active student participation by offering opportunity for all to speak during a lesson. Spend time in the beginning of the school year helping students understand what turn and talk looks like and sounds like by demonstrating with a student for the whole class.
