This Fluency Activity is a part of the Lesson 12, Unit 2, Grade 1. Certain fluency games that are played in class are good to play at home. Send home directions to the games so that parents can play with their children. Suggest ways parents can use different numbers to challenge their children and extend their learning during the games. This activity supports Grade 1's core fluency standard of adding and subtracting within 10. Notice the shift in the visual representation of ten, which transitions students into seeing ten as a single unit by the module's end.
