This Fluency Activity is a part of the Lesson 2, Unit 1, Grade 5. Fluency tasks are included not only as warm-ups for the current lesson, but also as opportunities to retain past number understandings and to sharpen those understandings needed for coming work. Skip-counting in Grade 5 provides support for the common multiple work covered in Module 3. Additionally, returning to a familiar and well-understood fluency can provide a student with a feeling of success before tackling a new body of work. Consider including body movements to accompany skip-counting exercises.
