Numeracy, like literacy, is key for students to access and make sense of their world(Unrwa, 2011). The main purpose of this study was to determine the numeracy level of the randomly selected grade seven students from two big schools in West District of SDO Calamba City during school year 2018 ? 2019. In order for the researchers to gather necessary data, the researchers deviced a tool called the Numeracy Inventory Device (NID) which measured the students? numeracy skills. After establishing the device?s validity and reliability, the researchers conducted the inventory to the respondents. Students have found to have basic numeracy knowledge and skills such as concepts, properties, and theoretical knowledge. However, they lack on analytical skills which is very significant in performing operations and solving word problems.Moreover, fraction is one of the most difficult areas in basic Mathematics as revealed in this study. However, it is the most utilized area in higher Mathematics.These findings helped out the researchers to identify students? strengths and weaknesses in terms of numbers which served as basis in designingintervention materials to improve the students? mathematics skills.
