{"abstract":"The study presented the results and findings of MULTI-TAB X (Multiplication Table Express), an innovation that taught multiplication skills in a fun and engaging way using manipulatives to make meaningful learning. The participants of the study were three (3) learners, consisting of one (1) Grade 2, and two (2) Grade 3 of La Suerte Elementary School in School Year 2022-2023. Data gathering methods used were teacher-researcher-made LEGNA pre-test and post-test, and Individual Multiplication Tracking Tool. Data were analyzed using graphs and overall percentage scores. The progress of the non-numerates was shown using the checklist of the Individual Multiplication Tracking Tool and the results of the teacher-researcher-made LEGNA pre-test and post-test. The researchers utilized the overall percentage of scores gained from the beginning to the end of implementation. These were presented through line graphs to illustrate the effectiveness of the innovative remediation. Based on the consolidation of the Individual Multiplication Tracking Tool, overall percentage scores were 65% (week 1&2), 74% (week 3&4), and 87% (week 5&6), and on the results of the LEGNA pre-test and post-test started from 20% to 80%. Therefore, MULTI-TAB X (Multiplication Table Express), a manipulative, that was user-friendly helped to increase the mastery skills and improve the multiplication skills of the non-numerates of key stage 1 learners of La Suerte Elementary School Year 2022-2023.","abstract_source":"original","authors":["Vangie Emnace","Anavilla Umalay","Marisa Maculbe"],"date":"2024-02-06","doi":"10.5281/zenodo.10623148","id":2489,"issue":10,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"f4026ede0d8926dfb20de32bfb75d8c0412524a07e4addcfdb9fb9f1cad42143","schema":"scimatic-article/1","title":"MULTI-TAB X (Multiplication Table Express):Improving Multiplication Skills of Learners in Key Stage 1","volume":16}
