ABSTRACT
This study aimed to enhance learners’ mastery in multiplication in TLE-Agri crop competencies in Grade 7 with a population size of 30. Data was acquired from a sample of students chosen at random by a lottery. Fourteen or 47% scored the average and 16 or 53% scored the poor level of mathematical skills in the Pretest conducted. Using the cutting-edge tool J-square, the researcher looked at how to improve learners' knowledge of multiplication. The results of the study showed that the number of learners who were at a poor level was reduced in the Posttest and that there is a significant difference (the two-tailed P value is less than 0.0001) in the scores using the J-square tool. The findings revealed that the difference is considered to be extremely significant, thus, this implies that the J-square tool is effective. It is therefore encouraged that teachers should use the J-square tool to enhance learners’ mastery in multiplication.
Keywords: mastery, j-square tool paired t-test, and place values
