The purpose of this study 1) analyze how much influence the Problem Based Learning model has on the understanding of elementary school students' mathematical concepts; 2) analyze how much influence the manipulative teaching aids-based learning model has on the understanding of elementary school students' mathematical concepts and 3) analyze how much difference the influence of the Problem Based Learning model and the Problem Based Learning model based on manipulative teaching aids to the understanding of elementary school mathematical concepts. This research is an experimental quasi study with a form of nonequivalent control group design. Samples of the study are from 3 elementary schools namely from class VI Public Elementary School number 2 Kalitengah, Public Elementary School number 1 Kangkung and Public Elementary School number 3 Kangkung. Purpose sampling technique was employed in this study. Data collection method includes observation, questionnaire and written test. Data analysis includes description of data, analysis prerequisite test, and hypothesis testing using t-test. Findings revealed there is a significant influence of the problem-based learning model on the understanding of mathematical concepts and confidence of elementary school students. There is a significant influence of the problem-based learning model based on manipulativeteaching aids on the understanding of mathematical concepts and the confidence of elementary school students and a significant difference in the influence of the model based on problem-based learning and problem-based learning based on manipulative teaching aids on understanding mathematical concepts and the confidence of elementary school students.
