The sample group was 40 Mathayomsuksa 3/2 students at Sriracha school in the 2020 academic year who were selected by a cluster random sampling. The instruments of this research consisted of seven lesson plans, a mathematical reasoning ability test with the reliability of 0.90, and a mathematical achievement test with the reliability of 0.89. The statistics for analyzing the data were means, standard deviation and t-test for one sample. The research results were that:</p><p>            1) mathematical reasoning ability of the sample group after using active learning management with think – pair – share technique was higher than the 70 percent criterion at .05 level of significance, and         2) the mathematical achievement of similarity after using with active learning management with think – pair – share technique was higher than the 70 percent criterion at .05 level of significance.</p> ER -
