This Fluency Activity is a part of the Lesson 9, Unit 3, Grade 1. Say a subtraction sentence aloud, saying "the mystery number" for the unknown answer (e.g., 5 - 3 = the mystery number). Call on a student to rephrase the sentence as an addition sentence (e.g., 3 + the mystery number = 5). Pause to provide think time. Students solve for the mystery number at the signal. Continue with the following suggested sequence: 5 - 3, 15 - 3, 6 - 4, and 16 - 4.
