Students have been shown the PK library catalog, and I have explained how to log in and put a book on hold, which I will then check out. Books can be picked up from the school office according to instructions from your child's teacher.
Realistic fiction as a genre is specifically contemporary, so books in this genre may include any of a variety of contemporary topics (e.g., racism, poverty, immigration, illness, loss of a loved one, family composition, interpersonal relationships, personal or group identity).
Of course any student is free to choose and obtain a book on his or her own. I encourage parents to take an interest in what your student is reading--not necessarily out of concern, but because it's super fun and enlightening to talk with these young people about what they are reading! (I know because I get to do so every week.)
I'd like to remind everyone that the Manhattan Beach public library is checking out books through its excellent Sidewalk Service.
The PK 5th Realistic fiction resource list in the PK catalog can be accessed from the right-hand side of the "Catalog" page. The books on this list are books I have read and know to be realistic fiction, or books cataloged as realistic fiction (in their "official" catalog entry), or books that have been listed as realistic fiction elsewhere (book reviews, lists created by public libraries, lists from literacy or education websites, etc.). Please note: I am not personally recommending all the books on the realistic fiction resource list! They are examples of the genre. It should still be up to each student and his or her family to make their own choices about reading material.
