This study focused on improving the numeracy rate of the various elementary schools in Candelaria East District in the division of Quezon, Philippines through the implementation of Project BIBO (Bridging Imperfections in Basic Operations). Addressing the gap of the learners who are not fully capitalizing on the basic arithmetic and fundamental operations can be done by implementing various numeracy interventions. A descriptive research design was utilized in analyzing the numeracy rates of the participating elementary schools before and after the conduct of Project BIBO. Samples were randomly selected while descriptive statistics and tests of difference were used in analyzing and interpreting the data. After a one-year implementation of the said project, results showed a pre-numeracy rate of 85.54% with a standard deviation of 0.108 and a post-numeracy rate of 94.46 with a standard deviation of 0.032. A t-value of -3.592 and a p-value of 0.003 provided sufficient evidence to conclude at 0.05 level of significance that there is a significant difference between the pre-numeracy and post-numeracy rates. It is therefore reflected from the results that the implementation of Project BIBO has successfully improved the numeracy rating of the various elementary schools in Candelaria East District, and thus, the continuous implementation of the project is hereby recommended as future actions within the wider range of scope in the district level.
