Ximena Garcia made a laser design for the Tower of Hanoi puzzle. You make two of each disk and glue them together for nice chunky pieces. We use dot stampers (for bingo sheets) to color the wood. Works great! The laser files are in this folder on our webpage. Tower of Hanoi is a model of exponential growth – number of

Here’s an excerpt of a twitter conversation. Day before yesterday Aida wrote to get access to some of our files and ideas. Yesterday she made this amazing version of Napiers Bones that is in the National Archeological Museum in Madrid. Today I’m inspired by her project and want to know more about this version and I want to see that

See how this grid folds into a parabola. More Parabola information in “owners manual” format by Michelle Tat. We laser cut the holes in the cardstock and added some laser etched lines to make the folds crisp. Find the laser files here. This thing is a great fidget and you would be surprised at the tenacity young children and even adults to

Women in Mathematics! Katherine Johnson calculated trajectories, parabolic and otherwise for NASA in the 1960s. Almost 70 years earlier Mary Boole invented curve stitching to teach the mathematical properties of parabolas to children. We made some really great foldable parabolas to connect to the work of both these women in math. Here’s the laser file – we cut the holes
