Multiplication Boxing Skill: Practice using the partial products (area model) algorithm. Materials: Deck of cards, with Tens, Jacks, and Kings removed. Queens count as 0. Players: 2 Object of the game: To get the larger product of two 2-digit numbers Directions: One player shuffles the deck of cards and places it number side down. Each player draws 4 cards and forms two 2-digit numbers. Players should form their numbers so their product is as large as possible. Players create 2 “boxing teams” by writing each of their numbers as a sum of tens and ones. Next, each player’s 2 teams “box.” Players multiply each member of their first team by each member of their second team. Then the 4 products are added. The player with the larger product wins the round and receives 1 point. To begin a new round, players draw 4 new cards to form 2 new numbers. A game consists of 3 rounds. Variations: Play with 10 sided dice, single digit and decades and roll dice to create number. Instead of earning a point for winning, students could add together their three products, and the person with the greater sum is declared the winner. Change the game by having students try to make the smallest product. Make the goal to be the person who has a product closest to 2500. Students would need to multiply, then find the difference between their product and 2500.
