The purpose of the study was to observe the understanding and motivation of second-grade Tier III students' achievement in skip-counting patterns by implementing music and non-music learning activities. The case study was performed using a qualitative design. A pretest-posttest and repeated measures design was used to analyze and triangulate the data with descriptive statistics. The computer software program, Atlas.ti, allowed me to develop two central themes, understanding of and motivation to learn skip-counting patterns. Video-recorded sessions, transcriptions, and observational notes allowed me to present important information into my results regarding student comprehension and behavior when completing various learning activities. The analysis of the data showed growth in their skip-counting abilities and also revealed positive motivation toward participating in the music learning activities. The growth was confirmed using posttests disposition and content scores, which improved from the pretests. The music and non-music learning activities provided insight for the artifact developed from this record of study in the area of skip-counting.
