This study uses a quantitative approach with a quasi-experimental research type with nonequivalent control group design. The experimental group in this study was class IVA which consisted of 28 students, and the control group was class IVB which consisted of 27 students at MIN 3 Jember. The data were obtained from filling in the student character questionnaire. Data analysis uses an independent sample t-test which begins with a prerequisite test in the form of a normality test and homogeneity test. The results showed that tcount = 2.613 > ttable = 2.006, and tcount = 4.979 > ttable = 2.006. This indicates that there are differences in pretest and posttest student character questionnaire scores between the experimental class and the control class. This shows that there is an effect of internalizing character education through discovery learning on set of numbers.
