ABSTRACT
This study aims to investigate how effectively a pocket book can be used as a teaching tool to improve students' numeracy skills in the Mathematics of Economics and Finance course. A quantitative method was used. A saturated sampling procedure was used to select 28 students. A correlation test and a comparative paired sample t-test were used to analyse the data. According to the findings, students' average pre-test score was 77.54, while their average post-test score increased to 93.39. The statistical tests revealed a significant difference in scores before and after the pocketbook was introduced, with a significance value (Sig. 2-tailed) of 0.000 (<0.05). Furthermore, the use of pocketbooks and the development of students' numeracy skills were found to be moderately positively correlated, with a correlation coefficient of 0.455. It can therefore be concluded that the pocket book of Economic and Financial Mathematics is an effective teaching aid for improving students' numeracy skills.
