The purpose of this study was to compare fine motor abilities of the kindergarten and primary students before and after training manual art activities after school. The subjects were 200 students studying in level 3 kindergarten, and grade 1, 2, 3 in primary students, secondary semester in academic year 2015 of Watdonkaidee Municipal School.

The experiment were carried out within 8 weeks, five days each week, and one hour a day. The instruments consisted of the program of manual art activities which had modified by the physical Education Institute and the fine motor ability test which modified by Pakakarn Noiniam (2013). Data Collecting by pretest-posttest fine motor ability before and after the experiment and data analyzed by using arithmetic mean, standard deviation and dependent t-test
