Truth and Lies
To play Truth and Lies start by placing the children into groups of three to five. Each child should reveal three interesting things about himself. Two of the things should be true while the third is a lie. The group can ask questions of the child and then must guess which of the three things is the lie. This activity is a great way for kids to get to know each other, but more importantly, it gets each child talking about something he finds interesting, but may not otherwise get to share. This game works well for children of all temperaments since the intimate setting and lack of competitiveness gives a greater sense of comfort.
Scavenger Hunt
Anytime children have to work together in groups for an extended period of time the conversation will eventually begin to flow. This makes a scavenger hunt ideal. However, if conversation is your main goal, rather than a traditional scavenger hunt, try a personal history scavenger hunt. Instead of finding objects the children will find out information about other kids. For instance, ask the children to find three kids with green eyes, an only child, someone who has a unique pet. Do not forget to encourage conversation within the queries. If the child finds another child who went overseas the "finder" should be prompted to ask a question like "Where did the person travel to overseas?" Give ample time to ensure that the children do not feel rushed and kids will be conversing freely.
Family Portrait
For this game you must first determine how many children are playing and figure out how many times you can break that group into groups of four or five. For instance, if you are working with 24 children you will have six groups of four children. Now create six surnames and write each surname on four note cards. Under the name of each family there should be family member title: mother, father, son, daughter, aunt, uncle. Now shuffle the cards and hand them out randomly. The children will then need to locate their "families." Yelling is not allowed. The kids must talk to each person to find their family. First family together wins.
