Abstract

Low learning motivation was observed among second-grade students at SD Negeri 01 Bojongsari, who showed limited enthusiasm, attention, and participation in mathematics lessons. This study aimed to improve students’ mathematics learning motivation through the Number House medium, a concrete medium for place value, number comparison, addition, and subtraction. A classroom action research design based on the Kemmis and McTaggart model was applied to 22 students selected through saturated sampling, consisting of a pre-cycle and two cycles of three meetings each. Data were collected using a ten-statement motivation questionnaire and a classroom observation sheet, with formative mathematics assessments as supporting data, and were analyzed descriptively using percentages and mean scores. The questionnaire score increased from 68.33% in the pre-cycle to 85.91% in Cycle I and 95.91% in Cycle II. Observed motivation rose from 46.21% to 73.48% and 93.94%, while the mean formative score increased from 64.09 to 77.73 and 88.07. These results indicate that Number House can support the improvement of mathematics learning motivation in the classroom studied, although the design does not show that the medium was the only factor behind the change. Teachers may consider Number House as an alternative concrete medium in the early grades.
