Wild War-Players turn up three cards and may do whatever math manipulation they wish with the numbers. Remember that two negative numbers make a positive product.

Improper Fraction War-Turn up two cards and make a fraction, using the larger card as the numerator. Product War-Turn up two cards and multiply.ДЄdvanced Product War-Turn up three (or four) cards and multiply.ДЇraction War-Players turn up two cards and make a fraction, using the smaller card as the numerator. This time, the greatest difference wins the skirmish. Subtraction War-Players turn up two cards and subtract the smaller number from the larger. The highest sum wins.ДЄdvanced Addition War-Turn up three (or four) cards for each skirmish and add them together. The next hand is played normally, with no cards turned down, and the winner of that skirmish takes the center pile as well.ДЄddition War-Players turn up two cards for each skirmish. For advanced games, however, the battle pattern is different: in case of a tie, the cards are placed in a center pile. VariationsДЇor most variations, the basic 3-down-1-up battle pattern becomes 2-down-2-up. Or shuffle the prisoner piles and play on until someone collects such a huge pile of cards that the others concede. Whoever has captured the most cards wins the game. When the players have fought their way through the entire deck, count the prisoners. The player who wins the battle captures all the cards played in that turn. If there is no greatest card this time, repeat the 3-down-1-up battle pattern until someone breaks the tie. Because all players join in, someone who had a low card in the initial skirmish may ultimately win the battle. The greatest of these new cards will capture everything on the table. Whenever there is a tie for greatest card, all the players battle: each player lays three cards face down, then a new card face up. The player with the greatest number wins the skirmish, placing his own and all captured cards into his prisoner pile.

This gives each player a 56-card deck full of the toughest problems to calculate. To give a greater challenge to older children, I make each player a double deck of math cards, but I remove the aces, deuces, and tens. With a normal deck of cards, however, I find they turn up far too many problems like 1 Г— 9 or 2 Г— 7. A math deck contains 40 cards, so a single game of Addition War lets a child work 20 problems, and he hears his opponent work 20 more-and if your children are like mine, they will rarely want to stop at just once through the deck.ДЄs my students learn their math facts, they need extra practice on the hard-to-remember ones like 6 Г— 8. Math cards are normal, poker-style playing cards with the jack, queen, king, and jokers removed. DonвЂ™t rush to look for these at your school supply store or try to order them through your favorite website. You will need several decks of math cards. Math concepts: greater-than/less-than, addition, subtraction, multiplication, division, fractions, negative numbers, absolute value, and multi-step problem solving. Have you and your children been struggling to learn the math facts? The game of Math Card War is worth more than a thousand math drill worksheets, letting you build your childrenвЂ™s calculating speed in a no-stress, no-test way.
