Cut the cardS apart and laminate as you see fit. Pass out a card (or more) to each student until all (32) cards have been distributed . The student with the first card reads the card: " I have the first card. Who has..." students listen and respond as their card is read. Continue until all cards have been read.
Students are given a slope and y-intercept and have to write an equation with their slope and y-intercept.
Having students place their cards under a document camera keeps all students engaged even after their card(s) have been read as they become the math checkers!
