This Fluency Activity is a part of the Lesson 24, Unit 4, Grade K. This activity helps students see numbers in relationship to the five and prepares them for using 5-groups with subtraction operations. Have students roll the dice, count the dots, and then draw the number as a 5-group. Observe to see which students erase completely and begin each time from one rather than draw more or erase some to adjust to the new number.
