JUST LIKE GO FISH!! Students deal 5 to 7 cards from the GO MULTIPLY deck (cards consist of either a product, or two factors). Place the remaining cards in a pile in front of all of the players. Players ask each other if they have the Product, or Factors that go with the Product or Factor cards in their hand. If they make a match they take another turn. If the can't make a match, they "Go Multiply".

I usually laminate and cut out the cards for durability. The game works best with 3 to 5 players, or you can remove factor groups to decrease the total number of cards for 2 players.
