User:Sherwin Balbuena/Intop card game

Intop card game is a mnemonic card game invented by Sherwin E. Balbuena, a Math teacher currently teaching at Cabitan NHS, Cabitan, Mandaon, Masbate. The playing of the card game is similar to any types of existing card games, only that Intop uses integers {from -10 to 10} and the four fundamental operations: addition, subtraction, multiplication, and division. It also includes the mnemonic devices LA US and LP UN, letter strategies which let the players remember the rules in operating integers. The card game is composed of three sets of cards: int cards (60 cards), op cards (30 cards), and selop cards (6 cards). An int card contains any of the integers ranging from -10 to 10; an op card contains any of the four fundamental operation symbols; and the selop card contains the four operation symbols. This card game can be played by 2, 3, and 5 players. In a master's thesis conducted by the inventor in 2010-2011, it was found out that the freshmen students of Cabitan NHS who had played the game performed better in operating signed numbers than those freshmen who underwent traditional instruction with integers.
