This Fluency Activity is a part of the Lesson 37, Unit 1, Grade 1. This activity supports students' ability to maintain their fluency with the counting sequence while also building the foundational skills for place value. Tell students to count along, alternating between the regular and the Say Ten way (e.g., 12, ten 3, 14, ten 5, etc.). Start at different numbers within 40. If students are ready, try counting back, too.
