It’s no secret. Team Desmos loves teachers and loves it when teachers use our tools to show their creativity. Inspired by your enthusiasm and your creative work, we make many of the activities on teacher.desmos.com publicly available to copy and edit. Want to have your students create virtual fields for virtual cows? Take Build a Bigger Field and make it your own! Want to add extension questions to Lego Prices? Go ahead and make a copy!
