This Fluency Activity is a part of the Lesson 13, Unit 5, Grade 1. Choose an appropriate Sprint, based on the needs of the class. If the majority of students completed the first three quadrants on the previous Sprint, move to the next Sprint listed in the sequence. If many students are not making it to the third quadrant, consider repeating the same Sprint. As students work, pay attention to their strategies and the number of problems they are answering to consider for future Sprint administration.
