I have, Who has:
• You will each be given a few cards and a coordinate plane.
• You need to know your cards and watch them each turn.
• The first person will say "I have ( , ). Who has ( , )?
• If your card matches the coordinate, you will read your card.
• Make sure to read your card loud enough for the class to hear.
