The low learning outcomes of students in class IVB at SDN 49 Kuranji, Padang City, in the subject of Mathematics served as the background for conducting this research. Several factors contributing to this condition include students' difficulties in solving problem-solving questions, learning materials that have not been fully adapted to the characteristics of the students, and instruction that remains teacher-centered. This research aims to improve student learning outcomes on the topic of Data Presentation through the implementation of the Problem Based Learning (PBL) model assisted by Canva in class IVB at SDN 49 Kuranji, Padang City. This research employed a Classroom Action Research (CAR) design with qualitative and quantitative approaches, carried out in two cycles. Each cycle consisted of four stages: planning, implementation, observation, and reflection. Research data were obtained from the assessment of lesson plan documents (RPPM), the implementation of learning activities, and student learning outcomes, with data collection techniques comprising both test and non-test methods. The findings revealed improvements across each cycle. The RPPM assessment increased from 93.74% to 100%, teacher activity increased from 88.20% to 95.55%, student activity increased from 89.28% to 96.42%, and the average student learning outcomes improved from 81.70 to 87.46. Based on these results, it can be concluded that the PBL model assisted by Canva has been proven effective in improving student learning outcomes in Mathematics learning in class IVB at SDN 49 Kuranji, Padang City.
