Assign a Tradition
If your family has a Turkey Day tradition, such as going around the table and saying what each person is thankful for, ask your older child to run the show. Thanksgiving is about gratitude and spending time with family; getting your preteen involved with both can keep him engaged. Ask your kid to kick things off by first sharing what he is thankful for, and then inviting others to do the same. Or, if your tradition consists of a pickup football game, put him in charge of rounding up players and making the teams.
