Intended to be used with Algebra 2 class after learning about linear functions in the beginning of the year. I print and laminated these cards, and then shuffle and pass out to students. Giving them a time limit (2-5 minutes, depending on their level) they need to find the person in the room that has the card that matches their card. Cards are paired by word/definition, picture/description, graph/slope, etc. Great activity to review vocabulary and gets students moving and talking!
