This activity, designed for a high school Honors Geometry course, involves isometric transformations (translation, reflection, rotation) in the coordinate plane. It includes specific transformation vocabulary and notations as well as reflections over the parent linear function. You can easily modify this activity to accommodate regular high school geometry students and honors 8th grade math students. I generally set up groups of three to four and have each individual student complete the activity and graph while collaborating and double checking with their group members to ensure that they don't "lose it". Then, I randomly choose one student paper and graph from each group to check as the group grade. After papers have been collected, I display the answer graph and enlarge using word (preview-fullscreen). The students then check the remaining graphs in the group to ensure they completed the task correctly (immediate feedback). They also get a chance to check their answers to the questions and we discuss if other transformations exist that do not fall in the category of an isometry. (Dilation)
I have also used this assignment as an individual homework assignment although it works better when students can catch each others' mistakes during the activity.
