The development of the Marbel Matma application for learning mathematics fraction theory in class IV

This study aims to ascertain the app Marbel Matma (Let's Learn Mathematics Together)'s applicability and effectiveness as a teaching tool in schools for improving students' comprehension of addition, subtraction, multiplication, and division of common fractions. It also aims to increase students' knowledge of learning mathematics. The ADDIE paradigm is used in this study's R&D (Research and Development) approach. (Analyze, Design, Development, Implementation, Evaluation). The study was carried out at SD IT AL-Maqom in Cimahi City, West Java's North Cimahi District. Teachers were used as media expert validators and substance specialists in the data gathering methods of observation, test, and answer surveys. The study was conducted using a test, and 10 students in grade IV who participated in the test were divided into one group for the pretest and posttest. Students receive an average pretest result of 48.00 and an average posttest result of 76.00 when using the normalcy test and the Paired Sample test. This demonstrates that pupils' test results on the subject have improved as a result of using the Marbel Matma program. Ordinary fraction division is a good way for primary school students to acquire numbers because it can help them comprehend it better.
