This Fluency Activity is a part of the Lesson 31, Unit 1, Grade 1. This activity reviews the Kindergarten standards of identifying 10 ones and some additional ones. This concept is foundational for Module 2, where students use the make ten strategy to add within 20. Tell students that 10 pennies are in the can. Have students close their eyes and listen. Drop 1 to 5 pennies in the can, one at a time.
