Guess Who I Am
Write the names of common Bible characters on name tags and keep them hidden away. As group members arrive, place a tag on the back of each attendee. After the entire group arrives, have the members mingle with each other. Each person then tries to guess who is on her name tag by asking questions of the other group members. For instance, "Is my character a woman?" or, "Was I one of the disciples?" When they have correctly guessed who they are, they can remove their tag.
Color Coded
Buy a bag of colorful candy pieces and have each person grab a handful as they pass the bag around. Give a topic for each color. For example, yellow is for career or high school. Go around the room and have each person tell something about himself related to the topics in his hand. The group will have fun eating the candy and learning interesting tidbits about each other.
This Is Your Life
Collect a bunch of pennies dated after the birth year of your youngest participant. As the group arrives for your meeting, have each member take a penny. Have the group sit in a circle, and then have each member share what her life was like during the year represented on her coin.
Roll of Fear
Just the sight of toilet paper at your meeting can get people laughing and help break the ice. As your group members gather, have everyone tear off as much as they would normally use, without revealing anything else. The point of the game is to have each person tell a fear for every square of paper he tore off. It's a lighthearted icebreaker that gets people laughing but at the same time fosters a sense of intimacy as participants share real fears.
