Guess My Number submitted by: Jeff LeMieux, October 2003 This narrative describes how I use my javascript tool, cataloged in the Math Tools digital library, in the classroom. Course: Math 7 Topic: Decimal Fractions Resource type: JavaScript Resource location: http://www2.whidbey.net/ohmsmath/webwork/javascript/guesser.html Math Forum catalogue entry: http://mathforum.org/mathtools/tool/12849 Story:  The computer selects some number of hundredths between 1 and 99. The student is to guess what the number is. The program keeps track of the number of guesses and tell if the guess is too large or too small. A small text pad is available for students to make notes about their guesses. Number sense, naming, and place value are all exercised by this script. The key part is the student must enter a value of hundredths Where and how I used this: Guesser is best described as a filler activity. It is used primarily when a student or students show difficulty with recognizing the value of numbers less than one in the decimal system. While stylistically it is no different then saying to name a value between $.01 and $.99, that learning transfer does not always occur. This script provides a different context to allow the student to experience 'another' way of looking at these decimal numbers.
