In this working paper which is being revised as part of a curriculum manual for later publication, the prevention and treatment of some classroom problems are summarized. Some guidelines are provided for teachers of preschool classes, dealing with the importance of consistent routines, of allowing the child a choice in his classroom work, and of avoiding confusion and frustration when tasks are too difficult for the child. Aggression, defiance or withdrawal are less likely to occur as children learn new concepts and are more in control of their feelings. The four chapters are headed: I. Developing Impulse Control Through the Daily Routine; II. Classroom Structure and Impulse Control; III. Teacher Planning Can Prevent "Management" Problems; and IV. Classroom Hints.
