Parameter increment is a value that will be added to the angle for each iteration.

Parameter angle determines how much the new segment’s angle deviates from the direction of the first segment.

Two points that determine a starting segment, with another segment extending from the second point.

Your scene should now include five characters: After you tap or drag the tool, you can either position each of the five glowing objects individually, or press the green check mark to accept them all in their current locations. So here it is: use the Mystery tool in the blank sketch area below to set the scene. Though their solution to this particular mystery is likely to be similar to yours, the body of the story-the clues found, the suspects pursued-will be their own.

Though the full version of Sketchpad remains the best tool for students to use in creating such a mathematical story from scratch, Web Sketchpad has progressed to the point that I can give you the beginning premise of the story (in this case a short mystery) and then put it in your hands to develop the plot, to find the clues, to identify potential suspects, and in the end to solve the mystery.Įven better, you can put this same beginning in students’ hands and let them develop their own plot, find their own clues, and pursue their own suspects. I described this process as being similar to the creative work students are expected to do in their English class: writing a short story in which they set the stage, introduce the characters, develop the plot, and so forth. My original post stressed the value of having students write mathematics by using The Geometer’s Sketchpad to construct their own interesting mathematical objects and in the process exploring what sort of mathematical story they might create as they elaborate on and speculate about their construction.

In the article* where I found this iteration, authors Al Cuoco, Paul Goldenberg, and June Mark challenged the reader to figure out how to predict the pattern from the input parameters. The post included an example of a simple Logo iteration, easily implemented in Sketchpad, that produces some very complex and interesting shapes depending on the values of several input parameters.
