Creative Math Art: Students can create any design on a graphing calculator provided equations involved can be written. For example a McDonald sign consists of 4 quadratic equations can be created. After watching the video students may like to create any of their designs based on linear function, quadratic function, cubic function, trigonometric function or their combinations.

OK, a wbd version of your manipulative set is ready to go. I have a credit byline on the page acknowledging that the idea originated from your movie, Iftikhar. :0)

It is located in my Box on my member page in the Mathematics folder under geometry.
