Learning strategies include two general categories of cognitive strategies and metacognitive strategies. The aim of this study was to investigate the effect of metacognitive strategies and play at home (UNICEF Proposed Package) on learning fundamental motor skills of children aged 5 to 8 in the pandemic of Corona disease. This study was a quasi-experimental intervention and in terms of research design, pre-test and post-test with the control group. Participants were 84 children living in Qom who were incidentaly selected and randomly divided into 6 groups. UNICEF Training Group, UNICEF Training Group with Metacognitive Strategies and Control Group (in the age groups of 5-6 years and 7-8 years). Raven and New York tests were used for cognitive and physical screening. Movement Assessment Battery for Children - Second Edition pre-test was taken from all participants. The intervention consisted of 18 sessions of UNICEF-recommended four games. The UNICEF Plus group conducted these exercises with a semi-structured interview to stimulate metacognition. The results of post-test with Mixed ANONA and ANKOVA showed that UNICEF and UNICEF Plus exercises improve children's fundamental motor skills; But despite the fact that UNICEF Plus training has led to better results in both age groups, this difference is not significant, and In other words, metacognitive exercises in these two age groups could not significantly improve. In general, it can be said that the exercises recommended by UNICEF were useful and the combination of these exercises with metacognitive strategies further improved children's motor skills.
