This Fluency Activity is a part of the Lesson 24, Unit 1, Grade 1. This activity addresses the core fluency objective for Grade 1 of adding and subtracting within 10. Point to a problem and call on a student to answer (e.g., 8 + 0 = _ ). The student answers "8," and then the class says the number sentence aloud, completed with the answer (8 + 0 = 8). If the student gives an incorrect answer, he or she then repeats the correct equation that the class gave.
