When selecting books for the classroom you should avoid once that include

offensive language or derogatory stereotypes that could be harmful or offensive to certain groups of students. Additionally, it is important to consider books that are written in languages that may not be understood by all students in the classroom, as this could create a language barrier and hinder their understanding and engagement with the material. It is also important to consider the length and complexity of the book, ensuring that it is appropriate for the age and reading level of the students in the class.
