We're starting with transformations, of which there are four types:
- translations (slides)
- reflections (flips)
- rotations
- dilations (zooming in or out)
First, I've given each student a section of tracing paper (to be kept in the plastic sleeve with the class assignment sheet and used for the entire unit). For many students this will be of significant help, using the tracing paper to mimic the motion. Second, look for patterns in the ordered pairs (x and y combinations) pre-image (the before) to image (the after). From the very beginning, I am going to be making my students record all of the ordered pairs, before-and-after. The patterns they will discover there will really help them.
Tonight's homework is for students to finish their reflection art project that we have been working on in class. Students must have recorded the coordinates pre-image and image, in order to get credit for this assignment when I check it first thing tomorrow.
