This Fluency Activity is a part of the Lesson 2, Unit 1, Grade 1. The Number Bond Dash is a new routine that will be used throughout Module 1. By using the same system, students focus on the mathematics, rather than figuring out the routine. Distribute Dash, face down, to students. Instruct students to flip their papers when they hear, "Go!" and complete as many number bonds as they can in 90 seconds.
