Mathematics is one of the main skills taught from elementary school to college, playing a role in developing critical and logical thinking patterns of students. However, many elementary school students have difficulty understanding mathematical concepts, especially spatial figures, due to the lack of supporting learning media. This study aims to explore the effectiveness of using Trimatra (three-dimensional) media in mathematics learning in elementary schools. Trimatra media, such as three-dimensional models of spatial figures, allows students to visualize and understand the characteristics and relationships between spatial figures in a concrete manner. The results of the literature study show that Trimatra media not only increases students' knowledge of mathematical concepts, but also motivates students to be actively involved in learning, increases critical thinking skills, and overall learning outcomes.

One effort to improve elementary school students' arithmetic (numeracy) skills is to use learning media in the form of an abacus. The abacus, also known as mental arithmetic, is a medium for developing thinking and calculating abilities in mathematics and is able to balance the abilities of the right and left brain. Therefore, SD 01 Ulak Karang teachers need to improve their skills in using the abacus, so that these skills can be mastered and provided to students well. The method of this activity includes basic level abacus training, namely (1) introducing body posture when using an abacus, (2) introducing the rules and how to operate/move the abacus beads, (3) introducing number notations represented by one or a group of abacus beads.  (4) introduce the technique of calculating addition and subtraction using an abacus and practice questions. Based on the results of this activity, the teachers at SDN 01 Ulak Karang Selatan are familiar with the technique of calculating with an abacus and can use the abacus to carry out addition and subtraction operations correctly and quickly. The teachers were very enthusiastic about being able to master all the techniques and calculation operations with the abacus.
