HRMARS - This study aims to identify the patterns of errors committed by respondents when doing calculations in division within 1 000 000 with 1-digit divisor. In addition, this study also examined the effectiveness of the use of teaching aid ‘Division with Pocket Doraemon’ in division among respondents in year 5. The design of this study is quantitative experiments that involved two groups which treatment and control groups. The instruments used in this study were pre-test and post-test. The study population comprised 232 respondents in schools in Kulai,Johor. While samples involved were 44 students’ year 5 in the school. The main objective of this study is to determine the effectiveness of the teaching aid, ‘Division with Pocket Doraemon’ in division. The data obtained was analyzed by using the Statistical Package for Social Science (SPSS) version 20.0. The study findings show a 26.1 % increase in the passing percentage in pre-test and post-test. The researcher used a paired sample t-test to compare the pre-test and post-test scores of the treatment group. By using the value of ? = 0.05 and the degree of freedom of 22, the researcher found that the value of t is -4.440, which falls within the critical region on the left side (t=±2.074). The mean of both pre-test and posttest was significant for the treatment group. It shows that there is a difference and a change in the mean between the two tests conducted by the researcher. Therefore,it can be concluded that the teaching aids introduced by the researcher helps respondents in solving division operations within 1 000 000 with a 1-digit divisor.
