This research aims to find out the numeracy abilities and motivation of students who use GeoGebra-assisted Problem Based Learning are better than students who use conventional learning. This research uses an experimental method with a Pretest-Posttest Control Group Design type of research and a quantitative approach, data collection techniques including tests, questionnaires and documentation. The material taught in this research is quadratic functions. The results of the research show that: 1) the pretest initial abilities of the experimental class and control class using the Mann-Whitney test obtained Asymp.sig values. (2-tailed) is 0.654 > 0.05, meaning is accepted; 2) posttest with the Mann-Whitney U test, the Asymp value was obtained sig. (2-tailed) is 0.000 < 0.05, meaning is rejected; 3) the average percentage results of the mathematics learning motivation questionnaire, the experimental class was 82% with solid criteria, while in the control class it was 69% with vital criteria. So it is concluded that the numeracy abilities and motivation to learn mathematics of students who are given the Problem Based Learning learning model assisted by GeoGebra are better than conventional learning.
