I broke a guillotine paper cutter once cutting rolls of newspaper. A paper cutter is an expensive piece of equipment for a public school, and they are remarkably durable so I was shocked when the bolt that holds the cutting arm just flat sheared off and the arm came away in my hand. My first thought was “Hmmm….how am I going to explain this one.”
A hush fell over the classroom, broken finally by a student with a penchant for the obvious. “Well, we’re gonna need a new paper cutter.” I was still counting my fingers. I blame Pinterest. See a more sensible lesson plan here that uses smaller tubes.
We were making icosahedrons out of newspaper in my 6th grade art classes. An icosahedron is a geometric form; a polyhedron with twenty faces. Per Wikipedia each regular icosahedron has thirty edges and twenty equilateral triangle faces with five meeting at each of its twelve vertices. This requires a LOT of newspaper tubes. A LOT that have to be cut to equal lengths. Twenty-five tubes per student. Of course a paper cutter is not designed to cut that many thick paper tubes. But it did for a while.
I was proud I could even pronounce icosahedron, since saying I am mathematically challenged is like saying the Titanic had a small leak. But newspaper was cheap and readily available from the library and classrooms. Ahhh…the digital world is changing that now.
I also was proving to my students how incredibly strong layers of newspaper are when rolled into a tube and taped into triangle faces. They worked together to construct their icosahedrons which were pretty impressive when they got them done. We had a blast making these, and I always wondered where they ended up when the students got them home.
