Abstract: This study sought to analyze how the current curriculum develops learners’ knowledge, skills, and attitudes based on teachers’ assessment and teaching experiences and their views on decongesting the curriculum by reducing the number of subjects. It used a self-made survey questionnaire with interview questions to describe how teachers assess curriculum theory and practice grounded on Aristotle’s theory on the categorization of knowledge (Aristotle, 1976) based on their teaching experiences and views on decongesting the curriculum considering Gardner’s Multiple Intelligences Theory. The data gathered were analyzed through quantitative and qualitative methods. It was revealed that the assessment of teacher-respondents was the same as the recommendation of the researcher that the road to improve literacy and numeracy development among Filipino children was to focus on Reading in English and Filipino/Mother Tongue, studying Arithmetic and Right Conduct or Character Education. These subjects were referred to as the 4 R’s – Reading in English, Reading in Filipino/ Mother Tongue, Arithmetic, and Right Conduct.
