This Fluency Activity is a part of the Lesson 6, Unit 1, Grade 1. For those students who are still developing basic counting skills, until this skill becomes automatic, provide a visual tool such as the hundreds chart in a place where they can easily see it during the game. By providing students with ongoing practice with counting throughout the year, they build and maintain their counting skills. This counting work is also foundational for later Grade 1 work with adding and subtracting within 100. Say a number between 1 and 100. When they hear "green light," students begin running in place and counting aloud together, beginning with the number given.
