“…A variety of representation forms comprising diagrams (Diezmann & English, 2001;Pantziara, Gagatsis, & Elia, 2009;van Garderen et al, 2013), number lines (Bobis, 2007;Gonsalves & Krawec, 2014) and pictures (Stohlmann, Yang, Huang, & Olson, 2019;Woleck, 2001) have been conducted across various mathematical topics (numbers, operations and probability). With the recent advancement in technology, researchers have investigated the potential of technology-based representations to aid mathematical sense making (Bakar & Karim, 2019;Özmantar, Akkoç, Bingölbali, Demir, & Ergene (2010), particularly in the support of the learner's visualizations. Researchers involved in these studies assert that students employ representations, as various representations support the students' understanding of mathematical concepts and facilitate problem-solution.…”
