This research was prompted by the weak mathematical problem-solving performance of eleventh-grade students at MAS Al-Washliyah Deli KM. 6 Medan in the matrix topic; an initial survey found that merely 55% of learners reached an adequate level of comprehension, falling short of the 75% mastery benchmark set by the school. The study set out to examine how the Discovery Learning model, supported by the Kahoot application, could enhance this ability. Using a pre-experimental, one-group pretest-posttest design, 30 students were purposively selected as participants. Data were gathered through an essay-based test built on Polya's problem-solving indicators, along with observation sheets and documentation, and were subsequently examined using descriptive statistics, the Shapiro-Wilk normality test, and a paired-samples t-test. Average scores climbed from 37.57 to 80.07, producing a mean gain of 42.50 points, with every student meeting the mastery threshold. The paired t-test produced t = -25.287, p < 0.001, and Cohen's d = 4.617.
