This Fluency Activity is a part of the Lesson 12, Unit 6, Grade 1. Choose an appropriate Sprint based on the needs of the class. As students work, pay attention to their strategies and the number of problems they are answering. If the majority of students complete the first three quadrants today, try giving them the next level of difficulty when administering the next Sprint. If many students are not making it to the third quadrant, consider repeating today's Sprint.
