This year Mr. Boughen and Ms.Wilson have been getting their students to do math on whiteboards and windows! The rationale behind vertical math is explained well in this article about building ‘thinking classrooms’ and Vertical Math. Both Mr. Boughen and Ms. Wilson have found that problem-solving on non-permanent vertical surfaces is a positive experience for students because they are more willing to make mistakes and take risks. In addition, they are able to see each other’s work around the room if they get stuck. They are better able to collaborate with each other in a low-stakes environment. Both teachers agree that this type of learning has worked really well in their math classrooms and are excited to try it out again next year!!
