I teach K-4 art and this book could not be better for my unit on patterns! The kids absolutely love following along with the patterns as I read. As we look it over a second time, I challenge them to find the patterns in the pictures (the book is overflowing with them) which really helps solidify the concept visually. Administration loves any excuse for the support teachers to incorporate literacy into our lessons so the book really is a perfect fit. Even the kids who are a struggle to get to participate in most things love adding the "POP" and "SHARK!"as we read. I highly recommend Pattern Fish to anyone - fun to read and see the kiddos really getting into it.
