We will read and discuss the book "Art Is" during the first kindergarten class this year. I love this book for many reasons. The balance of old and modern, the simple one-sentence-per-page text and the fun, questioning look at art it provides for students. Plus? Rhymes! I read this book to five different classes last year and every single time someone raised their hand to let me know the words rhymed. Gotta love kindergarten.
The lesson plan is available over on TpT if interested.
