An educational course for children designed to enable students, teachers, and others to learn about, recognise, build upon, and use their character strengths more. Strengths Gym draws on the latest research from Positive Psychology, that is the psychology of being happy, successful, and living life to the full. Each lesson explores one of 24 ubiquitous strengths of character or moral virtues. Each lesson contains Strengths Builders and Strengths Challenge exercises that have been designed for classroom, paired, and solitary work. The course provides a flexible, easy to use lesson format for ease of planning and is designed to encourage intrinsic motivation and satisfaction for students and young people in general. The course has broad applications outside of education, such as clinical and therapeutic settings, and is suitable for individual and group work. The materials can also be adapted for use with various age groups and abilities.
