This Fluency Activity is a part of the Lesson 2, Unit 4, Grade 1. This addition review sheet contains the majority of addition facts within 10, which are part of the required core fluency for Grade 1. Students are likely to do well with this activity at this point in the year. If not, repeat some addition fluency activities from Module 1, and use this activity as an assessment tool to monitor progress. 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, such as counting by ones from 46 or counting by tens from 3.
