The purposes of this research included: 1) To develop the experience learning plan through musical activities for developing mathematical skills of preschool children to be efficient in accordance with the criterion of 80/80; 2) To study the basic mathematical skills of preschool children from the experience learning through musical activities; and 3) To study the satisfaction of preschool children towards musical activities for developing the basic mathematical skills. The samples of this study were 20 kindergarten students in year 3 aged between 5-6 years studying in the second semester of academic year 2019 at Ban Huainamkam School, Bankhwao District, Chaiyaphum Province. The school was under Chaiyaphum Primary Education Service Area Office 1. The samples were selected through Simple Random. The instruments used in this research were: 1) twenty five experience learning plans through musical activities for developing the mathematical skills of preschool children with the suitability value at a high level of 4.48; 2) basic mathematical skill test of preschool children based on the experience learning through musical activities with the difficulty value from 0.46 to 0.73, the discrimination value from 0.47 to 0.84 and the reliability value at 0.95; and 3) questionnaire for satisfaction of preschool children towards the musical activities for developing the mathematical skills with the congruence value at 0.80- 1.00 and the reliability value at 0.75. The statistics used for data analysis were percentage, mean, standard deviation and alpha coefficient. The findings from this study were as the followings: 1) The efficiency of experience learning plans through musical activities for developing the mathematical skills of preschool children was at 83.96/83.25 that was higher than the specified criterion of 80/80. 2) The means of 4 basic mathematical skills of preschool children after the experience learning through musical activities could be chronologically arranged as the followings: sorting skill at 4.29, valuing numbers skill from 1-20 at 4.20, identifying and comparing skill at 4.07 and classifying skill at 3.82. 3) The satisfaction of preschool children towards musical activities for developing the mathematical skills was at a high level.
