This Fluency Activity is a part of the Lesson 32, Unit 1, Grade 1. Strong fluency with partners to 10 will be critical in Module 2 so that students can avoid using up too many of their attention resources on lower-level skills when they are addressing higher-level problems. Assign students partners. Partner 1 closes his eyes. Partner 2 quickly lays out the 5-group cards, numeral side up. Partner 1 opens his eyes and tries to match all partners to ten as quickly as possible.
