My teaching partner, LaNesha Tabb, and I love teaching our kindergarten and first grade students about this concept! Mirrors are books that contain story lines, characters, and experiences you can see yourself in. You can make personal connections to these books. You feel seen and heard after reading a book that is a mirror. A book that is a window helps you see into the life or experience of someone else. You may not be able to relate, but you can learn and grow from that story line or the book's characters.
