This work aims to submit an intervention proposal based on the use of Pedagogical Games for the teaching of Subject-Verb Agreement in relation to 1st and 3rd person plural in their proper order, and which were put into practice in an Elementary School among 8th graders. To that end, we have conducted action research with the following steps: identification of a problem, planning, intervention, and evaluation of the result. Regarding its theoretical contribution, this work was based on discussions dealing with grammar teaching and the teaching of subject-verb agreement, as well as with the functionalities of Pedagogical Games in the classroom. Previously, participating students were not used to properly differentiating the 1st and 3rd person in writing. Once this problem was detected, games were created. Using these games, we have registered a decrease in the occurrences of such errors – greater than 50% in each variable – which involved morphosyntactic constructs where there was no identification of the plural form in the 1st and 3rd persons plural.
