This activity was created to supplement Eureka Math Module 1 Lesson 1 with the objective to "Analyze to find two objects that are exactly the same or not exactly the same." Each student is given one card. When the teacher says, "On your mark, get set, go," students move around the room to find the person who has the exact same card. Once students find their match, they stand next to each other. Collect and redistribute the cards to play a second round. Time the students to see if they can find their match faster the second time.
