This Fluency Activity is a part of the Lesson 22, Unit 4, Grade 1. During the last few days of fluency, students have been reviewing the relationship between addition and subtraction using the context of a number bond. In this Sprint, students apply this knowledge to solve equations, first within 10 and then within 20. Students who reach the final two questions of the fourth quadrants are challenged to apply their understanding of analogous addition equations to analogous subtraction equations.
