# "Who Has" - Math Games

"Who Has" is a round robin of math questions and answers with each person playing each card he or she holds.

This is a family of math games. The way the game is played is always the same, but the content changes for each version of the game. The content might be anything from whole numbers and money for a first grade class to simplification of algebraic expressions to work with area and geometry to taking derivatives and integrating.

Directions:
Object:
In a group setting, to practice mental computation by answering a sequence of oral math questions. Ideally, questions should be projected one at a time (as with an overhead projector), so they may be read as they are orally asked.
Materials:
A deck of "Who Has" cards.
A list of the content of each card for projection on the overhead.
To Play:
• Distribute ALL the cards in the deck to members of the group or class except to the teacher or leader who is running the game at the overhead projector.
• Group members place the cards on the desk or hold them so that the printed side may be read.
• The leader places the list of all words on all cards on the overhead and covers all the words.
• The leader reveals the first line and reads aloud the first line asking, "Who has ...?"
• The group member who has the requested number, the member who holds the card which says "I have ...," answers aloud reading the entire card, saying, "I have .... Who has ...?"
• The group member who has the requested number, reads aloud the entire card saying, "I have ... Who has ...?" and play continues to the next group member. The leader reveals that line of the list so that a group member might listen to the question being read and might read it for him or herself off the overhead screen.
• Play ends when the first group member to read, reads the first card again, in answer to another member's question.
