Activity Sheets on the Application of the Four Fundamental Operations of Integers for Grade 7 Learners Using Open Approach

Low numeracy skills among learners, particularly in the difficulties with four fundamental operations of integers, remain a pressing issue in mathematics education. This action research aimed to develop and evaluate the effectiveness of activity sheets using an open approach in enhancing the numeracy skills of Grade 7 learners. The study employed a quantitative research design with qualitative support involving 38 grade 7 learners. The intervention implemented activity sheets was developed using the ADDIE model, which integrated the open approach to promote a deeper understanding of integer operations. Analysis of the quantitative data revealed a significant increase in the mean scores from the pre-test to the post-test, supported by the high engagement scores and qualitative data indicating a comprehensive collaborative learning experience. This reveals that implementing open approach activity sheets is an effective intervention that significantly enhances mathematical skills and engagement, thus supporting the use of learner-centered methodologies to better prepare students for advanced topics.
