In order to carry out the study on the accuracy of Turkish picture books, a rating rubric for English picture books was translated into Turkish. The Traffic Light Rating Rubric rates books as red (explicit inaccuracies), yellow (implicit inaccuracies or missing concepts) and green (correct concepts). As a result of the research, it was found that the findings for the Turkish books were consistent with the previous findings for the English books. In the majority of the books analysed, the geometric shapes were rated as incorrect (red). Given the importance of early mathematical study for long-term success, the Traffic Light Rating Rubric-Turkish Version is intended to provide guidance to book selectors such as librarians, parents and teachers, and ultimately authors and publishers who need to produce texts with the correct form.eninfo:eu-repo/semantics/openAccessEğitimEğitim AraştırmalarıMatematikDil ve Dil BilimArticle12366768910.16916/aded.13694581248909
