“…Many international researchers who are interested in mathematics such as (Cai & Lester, 2005;Dreher & Kuntze, 2015;Dwi, Subanji, Hidayanto & Anwar, 2017;You & Quinn, 2010) consider mathematical representations as the basic feature to teach and learn math, whereas researchers mentioned that mathematical representations are closely improving students' learning and understanding of math (Anthony & Walshaw, 2009;Greeno & Hall, 1997;Santulli, 2009;Tripathi, 2008). Nonetheless, there are only few studies that highlighted the role of the textbook and teachers in facilitating students' understanding through using mathematical representations (Bal, 2015;Bayazit, 2011;Yan & Lianghuo, 2006;Ulu, 2017) Reviewing the literature concerning mathematical representations; the work of Lesh, Post, and Behr (1987) was one of the most important in this area, they constructed a model of the various elements in which mathematical representations are structured. This model is consisted of five elements (Figure 1); (1) representations by written symbols such as writing numbers or symbols to express the math concept, (2) spoken representations which indicate expressing the math concept by words which allows often for more rephrasing the words and linking the concepts with other areas and life situations.…”
