Learning Mathematics is the ability to identify and count numbers, perform calculations of the general operations, understand concepts, relations and combinations. Mathematics is considered one of the difficult subjects from all other subjects in the primary level. In this thought, an elementary school teacher should know the techniques and method to find an effective way of teaching. As we know, elementary school pupils learn better if they are doing an activity and if they have something to hold or touch, they will be more interested in the teaching and learning process.
The objective of the study is to find out the possibility of using indigenous manipulative materials in teaching 90 pupils from Kalayaan Elementary School, Bagong Silang, Caloocan City and to find out the effectiveness of using these materials to improve and enhance the pupils' performance in Mathematics. The theoretical review will include giving pretest and posttest and by using the indigenous manipulatives such as wooden flats, longs units, plastic caps, sea shells, mussel shells, beans, place value bilao and others counters as instructional materials.
Based on the findings of the study, the following conclusions were drawn: The comparison of the mean score in the pre and post-test has shown that there is an increase of mean score from 5.83 in the pretest to the mean score of 16.34 in the posttest after the use of developed indigenous manipulative materials The MPS from 29.15 in the pre-test to 81.70 in the post-test marked a significant increase and attained much higher than the 75% mastery level given. This shows that the manipulative materials enhanced the pupils' skills in subtraction and multiplication. There was also a significant difference between the pre-test and post-test made by the researcher. Teaching exemplars such as lesson plans were made for the effective utilization of the developed indigenous manipulatives in the teaching-learning process.
