This Fluency Activity is a part of the Lesson 5, Unit 3, Grade 2. To keep student engagement high, you might modify the game for the class or for individuals. These are some adjustment suggestions: Two pairs at a table can "race" against each other rather than compete individually. This provides support and may reduce anxiety for students working below grade level or students with disabilities. Students working below grade level or those with disabilities may benefit from writing the new total after each turn.
