This I Have, Who Has, game is complete with 26 cards of tricky multiplication facts like 8x8 and 3x6. The cards contain the 3x, 4x, 6x, 7x, 8x, 9x and 12x facts.
There is a card labelled "Start" and "Finish" so it is easy to know who goes first. Hand out the cards to students and have the student with the start card go first. He asks the question on the bottom of the card, and the student with the answer puts down their card and asks their question, until you reach the "Finish" card.
