Have you ever played "War" with a deck of cards? The game is simple. Two (to three) split a deck of cards evenly and each member holds his or her cards face down as to conceal them. Members flip the top card simultaneously and the person with the highest card value wins. Play until one member remains and has all the cards - this person is the winner!
Just like "War," students can play Multiplication War applying the same rules. In this deck, there are 52 cards representing (mostly) fractions, two decimals, and one whole number. There are also three blank cards (which can be written on OR used as a wild card) and an instruction card.
Print page 8 on the back of each of the other pages to create a more professional feel. For sustainability, print on card stock and laminate.
Differentiate using whiteboards for students to show work and practice using multiple strategies. For further application, students may want to write each round and circle the higher value so that conversation may continue in the whole group. This page could even be used as an assessment.
My students LOVED this game and would even play during indoor recess - talk about a teacher's dream. :)
