Abstract

The purpose of this classroom action research is to examine the application of differentiated learning styles using the HIMATIKA concrete media to improve students' numeracy skills on grouping and comparing numbers 1–100 in second-grade students at SDN Bandungrejosari 1, Malang City. This research employed a qualitative approach with a two-cycle classroom action research (CAR) design. Data collection was conducted through observation and pre- and post-tests administered to 28 students. The results indicate that the differentiated learning styles approach using the HIMATIKA media can improve numeracy skills on grouping and comparing numbers 1–100. This improvement is evident from the comparison of pre- and post-test results, as well as observations that demonstrate active participation and increased conceptual understanding of students in the learning process.
