The classroom environment is at the heart of all that occurs in the prekindergarten classroom. In this half-day training, we will addresses how to create an optimal learning environment for prekindergarten children. We will focus on the presence of high quality, meaningful literacy and print centers and materials as well as instructional planning tools. To assist with this goal, the CIRCLE Classroom Environment Checklist (CEC) will be utilized. Teachers will learn the components of the CEC and how to use this tool to improve the overall design and management of the classroom and individual centers. We will also consider how to troubleshoot concerns that arise over the course of the school year.
