This study investigated pupil experiences and perceptions of two kinds of classroom-based physically active math lessons during the Moving Maths programme in a Finnish primary school context. Qualitative data were gathered in focus group interviews with 16 nine-year-old pupils. Pupils in the group with physically active breaks during math lessons expressed mixed experiences, while pupils in the group with physical activity (PA) integrated into math curriculum experienced increased positive emotional and cognitive engagement. It is concluded that integrating PA into mathematics lessons is a feasible pedagogical method, especially in the form of PA integrated into math curriculum goals.
