... of mathematics, while the Croatian version of the questionnaire Attitudes towards the Physical Activity Scale (APAS) was used for evaluating the attitudes toward physically active breaks with video materials. Differ ences between the initial and final measuring inside the same group were tested by the Student's dependent sample t-test, while for differences between the experimental and control group the Student's independent sample t-test was used. The obtained results showed that the ability to solve mathematical tasks in the experimental group has significantly improved when compared to the control one and that physically active breaks have a positive influence on the pupils' attitudes toward physical activity. The implementation of physically active breaks into teaching has an impact on pupils' productivity in the educational process, while at the same time their need for movement is fulfilled.
