I made a whole set of cards out of frustration. I made 80+ personalities with all kinds of information about each person. Using the cards Ss can try to guess the other persons information. The S who guess correctly first wins the card and then they find new partners.
The cards are here: Big Town
This page will explain more in detail but I've had success with these cards in every class I've used them in. That includes elementary school, junior high school, and college classes all ranging from 25-40 students.
The cards I have prepared are simple and for beginner to intermediate students.
I hope that helps or inspires.
