"Introduction: The physical education lesson in primary school can make an essential contribution to the psychomotor development of students. The purpose of this study is to highlight the progress made in the development of the Body Schema following the application of a specific intervention plan, progress verifiable in graphic form. Material and method: The target group consisted of 10 pupils (5 boys and 5 girls) aged between 6 and 7 years, pupils in the preparatory class who scored low and medium on the initial test. The experiment lasted 10 weeks, with 2 physical education lessons per week. The intervention plan included exercises and motor tracks focused on the development of the body schema. The “draw- a- person” test was applied. The scores were calculated for the Maturity Scale consisting of: Head Scale, Body Schema Scale and Clothing Scale. These scores underwent a qualitative interpretation of the differences between the initial and the final test. Results: There are visible differences of the “draw- a - person” drawings in the first and final tests of the students included in the study. The Body Schema was better integrated in the Maturity Scale, which means that the intervention program was efficient. Conclusions: Physical education and sports lessons with topics for developing the body schema were effective in recording the progress of this component. Key words: psychomotor skills, body schema, maturity scale, exercises, drawing. "
