Think of your classroom as an ecosystem—a set of interconnected components such as the classroom itself, the available resources, and the people who inhabit it. When these components are working well together, learning can be a joyous, exciting adventure. When one or more components break down, the entire system can be affected. With careful planning, organization, and monitoring, you can develop an effective system for you and your students. This chapter discusses ways teachers can establish routines, be organized, and use interesting activities with relevant content.
