Simulated Experimental Coin-Toss & Dice-Roll Data submitted by: Jeff LeMieux, June 2003 This narrative describes how I use my javascript tool, cataloged in the Math Tools digital library, in the classroom. Course: Math 7 Topic: Probability, Experimental Probability Resource type: JavaScript Resource location: http://www2.whidbey.net/ohmsmath/webwork/javascript/coindie.htm Math Forum catalogue entry: http://mathforum.org/mathtools/tool.html?rc=tool&new_id=786 Story:  Determining outcomes and the Fundamental Counting Principle are two of the foundation pieces of probability. This script marks the first time students are presented with two different kinds of independent events - the coin toss and the dice roll. After students have determined their experiments and listed their findings, this script allows them to experiment with larger numbers of trials. They still have to do the counting, but they can also check their counts with the data on the screen. Where and how I used this: This script is used as a supplement to the probability lessons. Normally, the students would have completed the labs and recorded their own data. Additional questions for these events would typically be independent investigations or homework assignments and the script would be available on the class lesson page.
