Therefore, it is necessary to develop the ultimate game media (snakes and ladders of mathematics) to improve students' mathematical problem-solving abilities in transformation material. This study uses the 4D development model (Define, Design, Development, Disseminate). This research was conducted at MTs Satu Atap Hidayatul Athfal with 14 students in class IX-1. The results of the feasibility test including the material expert validity test obtained a value of 75% and the results of the media expert test obtained a value of 80.56%, so that very valid criteria were obtained. The results of the practicality test from the teacher's response obtained a value of 97% and the results of the student's response obtained a value of 81.87%, so that very practical criteria were obtained. The results of the effectiveness test by conducting a post-test to measure the increase in students' mathematical problem-solving abilities after using the Ultama game media (mathematical snakes and ladders) on the transformation material obtained a value of 92.9% with very effective criteria. Based on the results of these tests, the developed product meets the criteria of valid, very practical, and very effective so that the Ultama game media to improve students' mathematical problem-solving abilities on the transformation material is worthy of use in the mathematics learning process. date: 2025 type: Thesis type: NonPeerReviewed format: text language: id identifier: https://eprints.untirta.ac.id/49754/1/Amanda%20Putri%20Maulidya_2225210094_Fulltext.pdf format: text language: id identifier: https://eprints.untirta.ac.id/49754/2/Amanda%20Putri%20Maulidya_2225210094_01.pdf format: text language: id identifier: https://eprints.untirta.ac.id/49754/3/Amanda%20Putri%20Maulidya_2225210094_02.pdf format: text language: id identifier: https://eprints.untirta.ac.id/49754/4/Amanda%20Putri%20Maulidya_2225210094_03.pdf format: text language: id identifier: https://eprints.untirta.ac.id/49754/5/Amanda%20Putri%20Maulidya_2225210094_04.pdf format: text language: id identifier: https://eprints.untirta.ac.id/49754/6/Amanda%20Putri%20Maulidya_2225210094_05.pdf format: text language: id identifier: https://eprints.untirta.ac.id/49754/7/Amanda%20Putri%20Maulidya_2225210094_Reff.pdf format: text language: id identifier: https://eprints.untirta.ac.id/49754/8/Amanda%20Putri%20Maulidya_2225210094_Lamp.pdf format: text language: id identifier: https://eprints.untirta.ac.id/49754/18/Amanda%20Putri%20Maulidya_2225210094_CP.pdf identifier: Maulidya, Amanda Putri (2025) PENGEMBANGAN MEDIA PERMAINAN ULTAMA UNTUK MENINGKATKAN KEMAMPUAN PEMECAHAN MASALAH MATEMATIS SISWA.
