This pie chart illustrates the proportion of visual components that most captured students' attention, based on observations and reflections. Color and icons were the dominant elements, making it easier for students to understand the material.

4.2. Board Game Interactivity and Student Engagement

The interactivity of board games, such as turn-based mechanics, challenging problems, and group collaboration, encourages students to actively participate in the learning process. Students become not only recipients of information but also actors directly involved in exploring the concepts of sequences and series. Observations show that student interaction increases, group discussions become more lively, and students become more confident in expressing their opinions. This is supported by research by Najah & Afifah (2022), who found that interactive elements in board games increase student engagement and motivation. Another empirical study by Pratama et al. (2023) also confirmed that interactivity in game-based learning strengthens understanding of mathematical concepts through hands-on and collaborative experiences.
