I have just accepted a job mid-year teaching a group of seventeen 3 year olds. The previous teacher did not seem to do anything with the children. I need to start over completely in teaching basic skills and managing behavior. This has been my first week in the classroom and I've observed and have tried to implement a routine. The class is loud, runs around a lot, and have a very hard time sitting in their chairs during snack or lunch time. I have spent the week focusing on a few minutes of circle time teaching alphabet, numbers, colors, and shapes, followed by a story. For the most part they love listening to stories. I have tried playing music with verbal directions such as "head, shoulders, knees and toes" and the "animal action" songs and these children just run around in circles screaming and not listening to the words at all. Trying to do simple activities with these children and art is a struggle, most of them hide under the table or run away from it completely. My assistant helps as much as she can but the children don't seem to listen to either of us. What can I do to implement an entire new routine and behavior management in February when these children have been in an unorganized classroom where they could do whatever they wanted since September?
