Step by step instructions are included for creating and editing lists, drawing a "picture", and then using list features on the TI-83/84 calculators to create transformations (reflections, translations, rotations, dilations) of the original image. Students must provide formulas to create new lists that will generate the desired transformed image. The lesson plan provides solutions for each of the desired transformations of a house with a chimney. Students may see both the pre-image and the image on the screen and determine if they placed the correct formula in the lists to create the desired transformation. Students love the activity!
