<![CDATA[This study aims to describe the implementation of the Interactive Malay Deli Picture Pattern Lapbook (LIPB-MD) in teaching picture patterns in fourth-grade elementary mathematics. This study employed a descriptive qualitative approach and was conducted at UPT SD Negeri 060816 Sukaramai, involving approximately 9–10 fourth-grade students who attended the learning activity. Data were collected through observation and documentation during the learning process. LIPB-MD integrated Malay Deli cultural contexts, namely Roti Jala and Kue Rasidah, to introduce increasing and decreasing picture patterns. The learning process was supported by GeoGebra to visualize picture patterns and Wayground as a group evaluation tool. The results showed that students responded positively and demonstrated enthusiasm when using LIPB-MD. Some students understood picture patterns more easily with visual support, while others still experienced difficulties because the material had not been previously taught. The group evaluation using Wayground showed different scores among the three groups, indicating variations in their performance during the activity. Furthermore, students were familiar with Roti Jala but were not familiar with Kue Rasidah. These findings suggest that LIPB-MD can serve as a supporting medium for mathematics learning by combining interactive activities, visual representations, and local cultural contexts. However, its implementation should be accompanied by step-by-step explanations and guidance according to students’ learning needs.]]>
