It helps teachers grow in confidence and creativity, and provides them with practical tools that will increase their own enjoyment of teaching and their pupils’ enjoyment of learning. Celebrating Strengths does not ‘teach’ positive psychology as an additional subject, but weaves it into the existing curriculum and life of the school. It is based around Strengths Gym, a programme for helping adults and children identify and use their strengths inside and outside the classroom through a cycle of festivals and storytelling. The methods have been tried and tested during four years of work in primary schools in North Lincolnshire, UK.The principles that underpin it, however, are universal and will readily adapt to early years settings, as well as those involving older children and young adults, and will be of as much interest to parents and carers as they will be to teachers. Celebrating Strengths will help anyone to flourish and be at their best - adults and children alike.
