Rebekah Keely (student and Innovation Center staff) and Marc Olsen (Math) collaborated on a laser cut version of Napier’s Bones, a manual mathematical multiplication manipulative for Marc to use with his Math students.
It takes a minute to get the hang of it, but it’s a quick and hands-on way to do multiplication.
Rebekah has mad Illustrator skills, and designed and perfected the file. It’s up on Thingiverse, if you’d like to grab one and make it.
