The problem of developing coordination abilities can be solved by using a coordination ladder in physical education classes at school. To determine the effect of a set of exercises using a coordination ladder on the development of indicators of coordinate (connect-unit) movements of children 8-9 years old. A pedagogical experiment was conducted at school No. 60 Kirov, (Russia) during the academic year. 104 students took part in the study. The children in the control group were engaged in the usual school physical education program, and the children from the experimental group additionally performed a set of exercises on the coordination ladder. All children were engaged in physical education 2 times a week for 40 minutes, a total of 72 physical education lessons were conducted in each class during the study period. The ability to coordinate (connect-unit) movements were determined by the test "Jumping on the spot". The Student's Tcriterion was used in statistical processing. After the end of the pedagogical experiment, the indicators of children in the control group improved by 13.2% (p>0.05), the positive dynamics can be explained by a natural increase in coordination abilities at the age of 8-9 years and the effectiveness of using the standard physical education program in Russian schools. The indicators of children in the experimental group improved by 34.9% (p<0.05). The indicators of coordinate (connect-unit) movements will significantly improve if children aged 8-9 will additionally perform a set of physical exercises on the coordination ladder during physical education lessons at school.
