Enhancing The Numeracy Skills of Grade 4 Pupils Through the Use of Sudomath Game Based Approach

This study aimed to determine the effect of the SudoMath Game-Based Learning Approach on the numeracy skills of Grade 4 pupils at a selected elementary school in Ozamiz City during the School Year 2025–2026. A classroom-based action research design using a single-group pretest–posttest approach was employed. The respondents of the study consisted of forty-two (42) Grade 4 pupils selected through purposive sampling. Data were collected using a researcher-made Numeracy Skills Test administered before and after the implementation of the SudoMath Game-Based Learning Approach. The research instrument was validated by education experts and tested for reliability, yielding an acceptable Cronbach’s alpha value. Data were analyzed using mean, standard deviation, and paired t-test through Jamovi. Findings revealed that the numeracy skills of Grade 4 pupils before the implementation of the intervention were categorized as Did Not Meet Expectations, while after the implementation, pupils’ performance improved to the Satisfactory level. Statistical analysis further revealed a very highly significant difference in the numeracy skills of Grade 4 pupils before and after the implementation of the SudoMath Game-Based Learning Approach. The study concluded that the SudoMath Game-Based Learning Approach is an effective instructional strategy in enhancing the numeracy skills of Grade 4 pupils through interactive and engaging mathematical activities.
