The teaching of Brazilian Portuguese language in elementary school prioritizes the standard dialect, and in many cases, it ignores the language the student brings to school. We realize that, despite several researches which have pointed out this issue, it is not given the due attention to the Linguistic Variations, which naturally migrate to students' writing, and being in many situations misinterpreted by pedagogical guidance teachers who prioritize the teaching of written language. Given this fact, this research aims to identify the Linguistic Variations in written texts: retextualization of comic book strips and letters, produced in the classroom by a group of students from public schools, and present reflections and questions from the assumptions of Educational Sociolinguistics, anchored in the Textual Linguistics. In order to give support to the theoretical assumptions established, and because they are important to the teaching of the language, we consider the conception of language, the PCNs-LP, the didactic book used, and the conception of text. The study methodology adopted is qualitative, focused on the interpretation of the interaction processes in classroom, considering the oral-written continuum. The analyses and discussion are done in two parts: analyses of the LDP and the textual productions, and the second part concerns the particular episodes of the initial phase of writing and the presence of Linguistic Variations which mostly occur in textual productions. The corpus comprises thirty-six retextualizations and twelve letters. We assume that it is not possible to ignore the modes of relationship between oral and written speech, for it is necessary for a work in the school institution the understanding of that relationship as a continuum, and that every modality has its own characteristics
