This Fluency Activity is a part of the Lesson 2, Unit 6, Grade 1. Give the appropriate Practice Set to each student. Help students become aware of their improvement. After students finish today's Practice Sets, ask them to raise their hands if they tried a new level today or improved their score from the previous day. Students complete as many problems as they can in 90 seconds. Assign a counting pattern and start number for early finishers, or have them practice make ten addition or subtraction on the back of their papers.
