This study determined the awareness of elementary teachers and the integration of One Town, One Product (OTOP) in teaching Technology and Livelihood Education (TLE). It used the descriptive-survey method of research. The respondents were the Grades IV, V, and VI teachers teaching TLE in Bulusan District, Division of Sorsogon Province for School Year 2021-2022, which were purposively chosen. The statistical tool utilized was the weighted mean. It was revealed that the majority of the local produce of Bulusan, Sorsogon under the OTOP program are pili products. The TLE teachers are much aware of the One-Town One-Product (OTOP) along with production, marketability, and LGU support. The teachers often integrate the OTOP in their teaching of Technology and Livelihood Education. A lesson exemplar was developed to further strengthen the integration of OTOP in the teaching of Technology and Livelihood Education. It was recommended that the manufacturer may develop other non-popular products utilizing locally available raw materials. The TLE teachers may improve their level of awareness of OTOP by visiting trade fair exhibits, patronizing the products, and coordinating with the LGU. The teachers may enhance the level of integration of OTOP in teaching TLE by showing product samples to the students and exposing them to trade fair exhibits where products are showcased and exhibited. The lesson exemplar may be submitted to experts for validation prior to its adaptation and implementation. Further study may be conducted which may include other municipalities involved in the OTOP program and other variables not covered.
