Abstract

This study aims to describe the process of learning mathematics on percentage material through the use of play money with the Indonesian Realistic Mathematics Education (PMRI) approach in class VII SMP. The PMRI approach is used to link mathematical concepts with real contexts, in this case buying and selling activities using play money. This research is a descriptive qualitative research conducted at MTs Al-Mu'aawanah Pemulutan, Ogan Ilir. The research subjects were seventh grade students. The instruments used include Learner Worksheets (LKPD), observation, and interviews. The results showed that the use of play money can help students understand the concept of percentage more concretely and contextually. Students become more active in the learning process and are able to connect the concept of percentage with everyday situations. The PMRI approach proved to be effective in increasing students' engagement and understanding of percentage material.

Abstract

Logic is an important foundation in mathematics learning because it shapes critical and systematic thinking skills. Introducing the concept of proof early on plays a strategic role in developing reasoning skills, identifying patterns, and providing simple arguments. This article aims to examine the role of logic in mathematics learning by emphasizing the importance of introducing the concept of proof from the outset. The methods used are a literature review of various relevant studies and descriptive analysis based on learning practices in early childhood education. The results of the study show that play, exploration, and concrete experience-based learning activities can improve children's ability to understand cause-and-effect relationships, make predictions, and convey logical reasons. In addition, social interaction and dialogue in the learning process have been proven to strengthen simple reasoning skills. In conclusion, the integration of logic and reasoning from an early age not only supports the development of mathematical abilities, but also builds the foundation for critical and analytical thinking needed for further education.
