This Fluency Activity is a part of the Lesson 13, Unit 1, Grade 1. This activity addresses the core fluency objective for Grade 1. Tell students to show 10 fingers. Instruct them to tuck 3 (students put down the pinky, ring finger, and middle finger on their right hands). Ask them how many fingers are up and how many are tucked. Then, ask them to say the number sentence aloud, beginning with the larger part (7 + 3 = 10), beginning with the smaller part (3 + 7 = 10), and beginning with the whole (10 = 3 + 7 or 10 = 7 + 3).
