The purposes of this research were 1) to examine the students’ learning achievement after learning through the learning management to conquer the O-NET on the topic of Set using varieties of teaching methods for MathaYomsuksa students of Phasang Wittaya School, and 2) to explore the mathematical concepts after the intervention. The sample was 36 students in Mathayomsuksa 6 who studied in the first semester of the academic year 2019 at Phasang Wittaya School, Surat Thani Province. Research instruments were seven lesson plans on Pre-O-NET on the topic of Set, a Pre-O-NET learning achievement test, and a mathematical concept test. The data were analysed using mean, standard deviation and t-test. The results were: 1) the students’ learning achievement was 14.33 (total score of 20), which was higher than the 50-percentage criterion with a statistical significance of 0.05 level, and 2) the students’ mathematical concept score was 20.31 (total score of 30) which was higher than the 50-percentage criterion with a statistical significance of 0.05 level.
