The purposes of this study were to develop a model of mathematics text reading comprehension by investigating the specific traits inherent in the mathematical reading as well as its related influencing factors; On the basis of both the literature review and the pilot study, The material utilized was the angle unit in the fourth-grade mathematics text. The groups of research subjects in the study, 336 elementary students in Kaohsiung. The research subjects formed the basis for the analysis of the mathematics reading comprehension skills, The main findings from this research are as follows.Mathematics reading was shown to have specific content-area reading skills, including prior knowledge of mathematics, reading comprehension for mathematical illustration, a good understanding of mathematical vocabulary and symbol, in concert with comprehension of procedural knowledge for plotting. In addition to the specific content-area reading skills, mathematical reading comprehension was comprised of reading comprehension, along with background knowledge of content-area reading. In relation to personal factors, mathematical reading comprehension had moderate correspondence with students' cognition.According to the above findings, suggestions were provided pertinent to the content-area reading model and teachers' teaching.
