in 24 evidence-based Strengths Cards

Use these beautiful cards to discover your individual character strengths and find new ways to put them into action. 

Based on years of Positive Psychology research, each card explains one strength, how the strength can be over- or under-played, and gives you some practical tips to increase it. 

Each box contains 25 beautifully designed cards (one for each strength plus a bonus card explaining over- and under-played strengths), a booklet explaining the Positive Psychology background and how to use the cards individually or in groups.

In our experience, children and young people love the idea of having character strengths and are just as curious to discover and use them. 

Based the evidence from Positive Psychology studies, each card in the pack explains one character strength in child-friendly language, relevant quotations from famous people and ideas for children and young people’s films, books and songs which illustrate each strength. Each card also provides suggestions for activities to boost each strength.
