Sarah Carter Profile Picture mathequalslove

Hi! I'm Sarah Carter. I currently teach high school math in Oklahoma (USA).

I love math, creating hands-on activities and resources, and crafting logic puzzles. I get extra-excited when I get to combine those passions to create quality classroom resources that are 100% FREE.
