I designed this slideshow for a supply teacher day. Grade 8 students were able to follow along with their laptops and produce good results. The three options each show you how the first few steps of complexity were added, and then jump to a finished product. The idea here is that the student can try out the idea but should add more details following their own thinking.

You can download the PowerPoint or just use the slides below. (Autoplay is off. Just click through using the left and right arrows.)
