This idea works well with both middle and high school youth groups. It works especially well with smaller groups. Pick a Saturday in November before Thanksgiving to have dinner with your youth. Each member signs up to bring one part of the Thanksgiving dinner (vegetables, sweet potatoes, pumpkin pie, etc). The catch is that they are supposed to bring someone they look up to (parent, older sibling, mentor). Before dinner, have each member tell who they brought and why they are thankful to God for them. A lot of supermarkets donate turkeys to church groups as well. This activity is always a favorite and it creates an atmosphere of not just a youth group, but a family united by God.
