This exploration was created to help your students master transformation rules. Ideally, this assignment is used in place of your typical, “take notes and practice.” Students use a manipulative (small cut out triangle) graph figures under the given transformations and look for patterns in the coordinates to come up with transformation rules.
Attached you will find a coordinate plane and sheet of triangles. Each student (or pair) needs one of each. Students will use these manipulatives as the work through the activity. For repeated use in multiple classes, it may be beneficial to laminate the triangles before cutting them out and placing the coordinate planes in sheet protectors. (This also allows for the use of dry erase markers).
Reflections over the line y = x, y = -x, and the y-axis are not covered explicitly in this activity. In my classroom, I encouraged earlier finishers to come up with these rules on their own and share with the class during debrief.
