The purposes of the research were 1) to compare the scores of 7th grade students from deductive learning activitites managaement with games on the topic of “Single Variable Linear Equations” to the standardized criteria of 75%, 2) to compare the achievement of the 7th grade students before and after using the deductive learning activities with games, and 3) to study the satisfaction of the students with the deductive learning activities with games. The research samples were twenty-eight 7th grade students of class one at Triam Udomsaksa Patanakarn Roi-Et School in the second semester of 2021. They were selected by cluster random sampling method. The research instrument consisted of lesson plans, an achievement test, a questionnaire, a recording form after teaching and an observation form. The statistics used were mean, standard deviation, percentage, one-sample t-test and t-test for dependent. The research results indicated that compare the mean score of 7th grade students from deductive learning activitites managaement with games on the topic of “Single Variable Linear Equations” was higher than the standardized criteria of 75% at the .05 level of the statiscal significance. 2) The findings revealed that the mean postet score after using deductive learning activitites managaement with games was higher than that of the pre-test score at the .05 level of the statiscal significance. 3) The overall satisfaction of the student with the deductive learning activities with games was at a high level.
