<![CDATA[Meaningful learning begins with student participation in learning activities that are still educationally centered. This is due to limitations in the use of teaching aids in implementing learning, resulting in students being less active when solving problems in learning. In this research, the aim is to improve students' ability to solve addition problems in mathematics by applying number pockets to grade 1 students at SD Godog 1. In this case, Classroom Action Research is chosen by applying the Kemmis and McTaggart strategy consisting of planning, implementation, observation, and reflection at the end of each cycle. The subjects of this research were 15 grade I students of SD Negeri Godog 1 Polokarto. Observations, tests, and documentation were implemented as data collection techniques. The results of this research prove that student learning outcomes can be improved through the use of media number bags in mathematics content in addition to material. This is reflected in the increase in "student learning outcomes in cycle I" from only 73% to 93% in cycle II. This success is quite satisfying because the indicators of "success presented in this research have been achieved. So, it can be concluded that there is a significant influence on mathematics learning outcomes in addition to material for class I students at SD Negeri Godog 1, Polokarto. Overall, the researcher contributed to increasing students' abilities in addition to material and teachers' abilities in increasing their own creativity in presenting interesting lessons.
