I'm thinking of a five-letter word

Think of a five-letter word that is not a proper noun and that doesn't have any repeating letters. Draw five lines near the top of the board. Students then must think of five-letter words (no repeating letters and no proper nouns). I write each word on the board and create columns under the five spaces. At the end of each word that a student suggests, write the number of letters that are also in the word they are trying to guess. For example, if my word is "ghost," then if a student gives me the word "house," I write a 3 at the end since three of the letters in "house" are also in "ghost." This requires students to really concentrate on coming up with good five-letter words. This game is always popular with my students.
