Cut out the cards; laminate for longer hold. Students get a card each and they walk around in the class and asking questions like: Who are you? They receive an answer and if they think they are a pair, they pair up and wait for the other students to fond their partner. When everyone has found their partner, you have them say who they are. E.g.: Salt & Pepper. The font used is Peggyfont, in case you want the nice look of the cards.
