This study was designed to determine the significant effects of using localized manipulatives and non-manipulatives in teaching mathematics to the learners mathematical skills. The study sample comprised one hundred eighty (180) selected grade 10 students in Pagsanjan Integrated National High School. The 180 respondents were from the four (4) grade 10 sections which are divided into experimental and controlled group. Experimental group had used localized manipulatives in learning the Math concepts, while controlled group are those who undergo Non-Manipulatives. The quasi-experimental method of research was used in this study to analyze and interpret the data being gathered to the respondents of this study. The descriptive quantitative research design was used in this study to determine the significant effects of using localized manipulatives and non-manipulatives in teaching mathematics to the learners mathematical skills. Survey questionnaires and examinations (Pre-test and Post-test) were used as the research instrument. The statistical treatment used to answer the questions stated above is the mean and standard deviation for the descriptive statistics, and the T-test for the inferential statistics. The study revealed that Localized Manipulatives and Non-Manipulatives in teaching mathematics has a significant effect to the learners mathematical skills. On the basis of these findings, it is recommended that educators may integrate the use of Localized Manipulatives into their discussion of mathematics concepts. Having known that most teachers apply Non-Manipulatives or direct instructions daily, it would be best if they combine it with Localized Manipulatives for a more development of students mathematical skills. In this way, they can create a learning environment that is more interactive, and students can realize the importance of each concept because they can see its application into their lives. Teachers can make use of both Localized Manipulatives and Non-manipulatives as part of their lesson planning. They may create a long-term mathematical knowledge and skills to students through interactive activities that combination of Localized Manipulatives and Non-Manipulatives can provide. Moreover, teachers may prioritize on improving the higher-order thinking skills of the learners, so they can teach them make decisions in a reasonable manner.
