## Welcome to CollaboMath!

Collaborative Mathematics offers a set of 16 mathematical problem solving challenges, each presented in a short video. Problem solvers are invited to watch the videos, give the problems a try, and create a response video in which they explain their solution.

The individual challenge pages are linked below. Each page includes a student handout, and many include links to response videos submitted by participants. Teachers may also wish to visit our curriculum page, where we offer a lesson outline with tips for structuring a class period around exploring and discussing a Collaborative Mathematics video challenge.

Julie T. from Superior, Wisconsin says: "I teach a higher level 5th grade math group and the challenges have been some of the best discussion this year! The challenges have forced them to think about their thinking and explain it to others."
