This Fluency Activity is a part of the Lesson 3, Unit 4, Grade 1. This activity assesses students' progress toward mastery of the required addition fluency for first graders. Since this is the second day of this activity, encourage students to remember how many problems they answered during the last lesson and celebrate improvement. Students complete as many problems as they can in three minutes. Choose a counting sequence for early finishers to practice on the back of their papers. When time runs out, read the answers aloud so students can correct their work and celebrate improvement.
