Educational games provide a fun introduction to new material and a review of mathematical algorithms. Specifically, games can be designed to assist students in developing mathematical skills as an incidental consequence of the game-playing process. The programs presented in this article are adaptations of board games or television shows that students may be familiar with, making the experience more memorable for them. Suggested games are: "Word Whiz," which plays the word game that most resembles the toss-up words on the television show "Wheel of Fortune®"; the second calculator game simulates the television game show "Deal or No Deal®," in which contestants try to identify a briefcase with 1 million dollars in it; the third calculator program simulates the familiar board game "Battleship®" (by "Hasbro™]), in which players try to sink one another's ships by identifying coordinates on a grid; and the fourth calculator games is from the 1980s television game show "Name That Tune®," where contestants were given a chance to win money by identifying a song after hearing only several notes. The calculator game "Name That Graph" follows the same pattern, using a variety of graphs instead of songs. All of the programs can be downloaded to a computer and then transferred to calculators using programs provided by each calculator manufacturer. Students who seem reluctant to get involved in classwork or homework enjoy the opportunity to do mathematics while playing a game. These programs involve an element of discovery in a game format that provides students the incentive to practice mathematical concepts in an entertaining and engaging fashion.
