Engaging Math and Science with Vertical Non-Permanent Surfaces
Our senior math and science teacher, Mr. Coulter, is transforming the way students engage with problem-solving using Vertical Non-Permanent Surfaces (VNPS)—a strategy from Building Thinking Classrooms in Mathematics by Peter Liljedahl. After the lesson introduction, students work in randomised small groups of three at whiteboards around the room. One student acts as a scribe while all three students discuss and collaborate regarding various problems and processes. This approach fosters conversational learning, encouraging students to talk through their thinking in a
