Great Book for Both Teachers and Students
Format: Hardcover
“The Yellow Bus Book” is such a meaningful and versatile read. It works perfectly for professional development with teachers, but it’s also great for sharing with kids. The message is simple, relatable, and powerful encouraging kindness, connection, and a positive mindset in school communities. I love that it opens the door for great conversations, whether you’re using it in a classroom, staff training, or even at home.
