In The Summit math classes, students are frequently seen clustered around small whiteboards on the walls. This work has been carefully designed using Building Thinking Classrooms in Mathematics by Peter Liljedahl. Liljedahl\u2019s research shows that when standing in small groups at vertical whiteboards students start tasks more quickly, stay on [&hellip;]"}
