I had made a couple of models several years ago, but wanted to add to my collection. And I want to have the students to actually make some this coming new year. I used the 2015, 2014, 2013 AP Calculus AB exam questions. Made an enlarged graph with Desmos, made a table of values with Excel, and some corrugated cardboard from old boxes stored for that “one day I’ll use these.” I have used small nails to pierce the cardboard base that then goes into the standing card slices. I haven’t done that step yet since my nails are in my classroom. I may use the stickytac to hold the slices. Hope to post pics when I put this together.
Enjoyed looking at other examples on the web
