This study aims to improve the numeracy skills of fifth-grade students at SDN Mangaran 04 through
the application of Wordwall-based interactive learning media. The main problems faced are low
numeracy skills among students, particularly in understanding the meaning of numbers in story
problems, accuracy in basic arithmetic operations, and simple reasoning skills in determining solution
strategies. This study used the Classroom Action Research (CAR) method with the Kemmis and
McTaggart model, which was carried out in two cycles. The research subjects consisted of 30 fifth-
grade students. Data were collected through numeracy tests, observations, and interviews, then
analyzed descriptively, quantitatively, and qualitatively. The results showed an increase in students'
numeracy skills after the implementation of Wordwall, marked by an increase in the average numeracy
score from 22% in the pre-cycle to 80% at the end of Cycle II, as well as an increase in learning
completeness from 22% to 80%. This improvement occurred because Wordwall facilitated repetitive
numeracy exercises, presented contextual questions through gamification, and provided immediate
feedback that helped students correct their mistakes and strengthen their understanding of concepts.
Thus, the use of Wordwall-based interactive learning media was found to contribute positively to the
improvement of elementary school students' numeracy skills, especially in the context of schools in
areas with limited learning facilities.
