Pete the Cat by Eric Litwin. Seriously, life doesn't get much better than singing and reading with the kindergartners.
If you have not yet read Pete the Cat, I highly recommend reading it and singing with this song: Pete the Cat Song.
....and here is Pete Rocking in My School Shoes.
Eric Litwin's new book Pete the Cat and His Four Groovy Buttons comes out next month--we can hardly wait!
