This manual is designed to assist Alberta (Canada) teachers in identifying social behavior difficulties in their students and promoting prosocial behavior through the use of various classroom activities. A social skills diagnostic screen is provided to aid teachers in assessing personal and interpersonal development, social reasoning skills, and classroom behaviors that are appropriate for children. Role playing activities that emphasize these skills are suggested, as well as ways to handle negative behaviors. Also discussed are nine categories of group activities for use in the classroom: (1) getting to know others; (2) rules and respect; (3) responsibility; (4) listening skills; (5) making and keeping friends; (6) decision-making; (7) helping children say no to dangerous or illegal activities; (8) problem-solving; and (9) compromising.
