My name is Cale Moore and I am a product design student at the University of Kansas. For my senior thesis, I am designing a series of math manipulatives (like tangrams and pentominoes) for higher levels of math (trigonometry, precalc, calc, etc.). If you are a high school math student, it would greatly help my project if you would fill out a short survey concerning your use of manipulatives in the classroom. Please follow the link below to participate.
