Translation from words to symbols is undeniably one of the solution processes in solving word problems that can be considered critical (Bardillion, Jr. 2004) cited by Dela Cruz, et.al (2014). Failure to translate the verbal statement to mathematical symbols can lead to incorrect solution. This study aimed at giving remedy to the least mastered competency in translating verbal phrases to mathematical symbols and improving the academic performance of the Grade 7 students at Tabuk City National High School, Tabuk City Division, School Year 2017-2018 using the Strategic Intervention Material developed by Ms. Apple Jean G. Yecyec (n.d.). This study focused on the fifteen (15) identified students having a score of 1-5 on a given formative test. A teacher-made pretest and posttest was utilized. The participants had a ?Very Low? performance on the pre-test at 24.65% level of mastery with regards to translating verbal phrases to mathematical symbols. Results showed there was a significant difference between the pretest and posttest of the participants. It implies that the strategic intervention material by Yecyec on translating verbal phrase to mathematical symbols is effective in improving the mastery level on the least learning competency. Thus, the Strategic Intervention Material (SIM) by Yecyec on translating verbal phrases to mathematical symbols is strongly recommended for dissemination and utilization.
