Aimed at pupils aged 10 to 12, the initiative has been created by BBC Bitesize and the mental health charity YoungMinds.
It includes videos, interactive games and tips and advice and supports pupils during their last term in primary school and through their critical first weeks at secondary school.
In September 2019, 752,528 children will move up to secondary school across the UK but research from the UCL Institute of Health Equity in 2015 found that, for some young people, it can negatively affect their social, emotional and academic outcomes leading to less engagement, lower attainment, reduced confidence, increased anxiety, loneliness and behaviour issues.
The resource aims to tackle these issues and also includes peer-to-peer advice, practical tips for parents, and classroom clips and resources for teachers.
