This Fluency Activity is a part of the Lesson 17, Unit 7, Grade 4. These are games that students can play with family members to maintain skills over the summer. It may be appropriate to invite parents and siblings to learn and participate, perhaps during a math or parents' night. Students may consider game partners and make adjustments accordingly. For example, if played with a younger or older sibling, games may include math appropriate for siblings. Discuss with students how to best adapt the games for their personal summer experiences.
