Have one person start with the letter 'A' and tell one thing they are thankful for that starts with that letter, for example, 'apples'. The next person will then say, "I am thankful for apples and bananas." (starts with 'b'). The next person will say, "I am thankful for apples, bananas, and cheese!"
Continue through the whole alphabet and see how far you can get! It's a fun challenge to not only think of something that starts with a particular letter, but to also have to remember everyone else's answers!
Last night we played this game and discovered that family members were thankful for goats, elephants, and underwear, among other things. It's a great way to add a little laughter and an attitude of gratitude to your Thanksgiving celebration! :-)
