What is a classroom and who does it belong to? The students or the teachers? Teachers by nature of being the teacher of a classroom have all the opportunity to customize, organize, color, add, subtract, and change their classroom but students do not. In some capacity, teachers share this personalization when placing student work on the wall but I think this can be taken further. A great activity to initiate the student personalization of their classroom is a cork board. I use this for younger students by asking them to bring in and pin up a picture of something or someone they like from outside of school. I start the activity by pinning up a picture of my cat Donut and telling a story about her. Using a cork board with upper school I use this activity for students to brainstorm how their lives intersect with a topic of the curriculum.
