You choose library books for students to sort into realistic fiction and NOT realistic fiction. Then put the QR codes on the book covers. (When scanned, codes reveal if the book is REALISTIC FICTION or NOT REALISTIC FICTION.) Students are directed to read the book summaries on the back covers or inside flaps, sort the books into Realistic Fiction and NOT Realistic Fiction, then scan the code on each book to check their work. A simple center to set up and one that students will enjoy as they look through your library books and use the QR codes to check their work.
