This research concentrates on the verification that there was a link between the pedagogical knowledge and mathematical skills to student’s achievement in the new normal. This ex-post research looked into the relationship and predictive degree of teachers’ pedagogical knowledge and mathematical skills to students’ mathematical achievement. Teachers’ pedagogical knowledge was found to be high in the study, whereas teachers’ mathematical skills were found to be very high and the level of students’ achievement in mathematics was also found as high. Both Teachers’ pedagogical knowledge and mathematical skills do not have a significant impact on students’ achievement in mathematics. The findings showed the importance of environmental context and appropriateness of online platforms in various strategies for improving students’ mathematical achievement. The findings suggest that virtual platforms should be suitable for the instructional strategies and capabilities of teachers and the students. Environmental context also is very vital in this new normal setting of learning, especially in the provinces where internet connection is not stable in most places.
