I like to play two truths and a lie. Have one child come up with two truths and a lie about that tribe. This is always fun for the upper grades. Give the kids a word and challenge them to see how many words they can make out of it. Words must be three or more letters.
Students ask yes or no questions to determine what is in the bag.
