The development of child’s motor skills implies the ability to perform motor activities. Performing different movements is a crucial part of child development and acquiring motor skills. In this research we focus on the development of biotic motor knowledge that helps a child perform certain movements in space. The aim of this study is to measure the motor skills performance level, in children ages 5 to 7, as they perform certain tasks measured through the motor skills development assessment, comparing the results in two measurement points. Our method focuses on measuring motor skills through motor skills assessment with 4 domains, each of which has 3 exercises with a total of 12 exercises: first test includes 3 exercises in mastering space domain, second test contains 3 exercises to master obstacles, third test includes 3 exercises to master resistance domain, and fourth test is comprised of 3 exercise to understand child’s ability to use objects. The final results show the improvement over the initial pre-assessment measurements.
