First, pass out the family tree and teach the kids the vocabulary at the bottom, like brother and aunt and cousin. Then, practice the names of all the people in the family tree. Do a few practice questions to check if they remember the meanings, such as, "Who is Bill's aunt?" and so on. Then pass out the bingo sheet. Let them write their favorite family members in the spaces of the bingo sheet. Then give them more questions like, "Who is Bill's aunt?" If they have Bill's aunt written in, they can draw a circle around it and try to get bingo.
