This online activity is based upon the television game show in which contestants try to guess a word or phrase. Students are given a partially completed word puzzle and asked to choose a vowel and three additional consonants. The activity is part of the Figure This! collection of 80 challenges that demonstrate real-world uses of mathematics. This challenge notes the importance of language structure and letter frequency in voice recognition software and cryptography. Students are encouraged to approach the challenge by thinking about which letters are used the most frequently. The solution offers a complete letter frequency table. Related questions offer additional codes to break, as well as links to online resources about the Enigma Machine. Copyright 2005 Eisenhower National Clearinghouse
