A Texas middle school teacher has been fired after assigning an unapproved illustrated version of Anne Frank's Diary to her eighth grade reading class. Per a report from KFDM, a spokesperson for Hamshire-Fannett ISD, located south of Beaumont, released a statement confirming the teacher was sent home on Wednesday after reading a passage from Anne Frank's Diary: The Graphic Adaptation in which Frank wrote about male and female genitalia. An investigation into the incident has since ensued.
The article notes she read from the book and then the author described the book.
And even if she did, students at that age should be able to read or hear the entire book.
