The research followed the principles of Didactic Engineering as a research methodology, respecting all its stages. The didactic sequence was grounded in Teaching through Experimental Activities and consisted of 17 activities. The experimentation was carried out in September 2025 with teachers from the public school system. Initially, a socio-educational questionnaire was applied, followed by the didactic sequence and the in-depth questions directed to Mathematics teachers from the public education network of the state of Pará. Statistical analysis was conducted, revealing results that confirmed the relevance of the experimental activities and of the proposed sequence in promoting meaningful, reflective learning aligned with current curricular guidelines. The results indicate that, in most activities, teachers fully agreed that the proposal is feasible for application in the 9th grade of middle school; however, only in activities 3 and 15 did responses indicate partial agreement regarding feasibility at this level. The validation carried out by the teachers—most of whom were favorable to the applicability of the proposal—demonstrated pedagogical consistency even in contents widely recognized as complex, such as radication, indicating that the teaching methodologies employed were responsible for the positive results obtained in the experiment. Consequently, an educational product entitled Math Solver Software Tutorial was developed based on this research and the results achieved, with the purpose of enabling other Mathematics teachers to become familiar with and use it in their classes.PPGEM - Metodologia para ensino de matemática no nível médio
