Keywords: Student Learning Outcomes, Volume of Cubes and Blocks, Group Investigation, Number Head Together, Make a Match

The problem in this research is the low learning outcomes of students on the content of mathematics lessons on the volume of cubes and blocks. The reason is that learning is one-way, as well as learning that uses models and methods that are still not suitable because there are no activities that make students actively involved. Efforts to overcome this problem are by doing learning using a combination of Group Investigation, Number Head Together, Make a Match models.

This study aims to describe the quality of teacher activities, student activities, and improve student learning outcomes using a combination of Group Investigation, Number Head Together, Make a Match models. This research uses Classroom Action Research which consists of three meetings. The subjects in this study were 14 fifth grade students at SDN Basirih 5 Banjarmasin in the 2021/2022 academic year. The types of data in this study are qualitative data and quantitative data. Qualitative data obtained through observation of teacher and student activities and quantitative data obtained through individual written test techniques. Data analysis is calculated based on the percentage scale and indicators of classical learning completeness that have been determined.

The results of this study indicate that teacher activity has increased, which at meeting 1 only reached 77.77% with the "Good" category until meeting 3 increased to 100% with the "Very Good" category. Student activity at meeting 1 reached 35.71% with the category "A small number of active students" until meeting 3 increased to 100% with the category (All Students are Active). Student learning outcomes in the cognitive domain at meeting 1 reached 28.57% at the meeting. 3 increases to 100%.

Based on these findings, it can be concluded that learning using a combination of Group Investigation, Number Head Together, Make a Match models is proven to increase teacher activity, student activity, and student learning outcomes. It is suggested that the use of this model is an alternative in increasing student interaction and involvement in learning activities in improving learning outcomes.
