A Math Teachers’ Circle is a place where middle school math teachers (also open to high school and elementary teachers) and mathematicians come together to explore problem solving approaches with interesting and fun math problems and to share classroom experiences and success. During the three-day workshop, teachers will participate in a process of learning that puts the enjoyment back in mathematics through the investigation of intriguing problems. The Heartland Math Teachers’ Circle at MNU provides guidance and support for promoting critical thinking and problem solving in the classroom.
