Remix of math spinner by FunFunBoy. I liked his clicking/locking mechanism for the dials, but wanted more. I wanted something where I could have students model the four basic operations in math and also to show inequalities. I increased the font size and added the different equality symbols. In addition, I added markers to the end caps so the student would know which equation they were working on. When printing, print 2 end caps, and 8 number rings. Everything else is just a single print.
7/5/18: I have added a blank turntable-ring so you all may may your own custom designs or just need a spacer.
