Students and teachers from 3 schools in the Foothills School Division posed problems for each other to solve. They embarked on an online threaded discussion while investigation and solving these problems. The purpose of this project was to sponsor mathematical conversation around good problems. We wanted to create more purposeful mathematical talk and activity. What do we know? What do we do when we don’t know what to do? What do we need to know? How can we use models to help us? How do we know if we have a good model? What have we learned? How does math relate to our personal experiences?
