This Guide has been designed for teachers supporting children in their return to school in the wake of the pandemic. It opens with a set of general group-building exercises, followed by themed activities focussing on 16 key life skills supporting the personal, cognitive and interpersonal development of children. The exercises are suitable for a wide range of different age groups from pre-school to secondary school. The exercises could also be combined with sports and leisure activities in clubs or community centres, and in safe spaces for children in humanitarian settings.
