I've been working on a list of some of my favorite picture books that allow you to mix it up by adding a song.
I Ain't Gonna Paint No More by Karen Beaumont Just plain fun. I give kids paint brushes so they can act this one out.
May There Always be Sunshine by Jim Gill A nice sweet song. Makes a good closer to a storytime session. Can choose a couple pages to sing at baby storytime also.
The Soup Opera by Jim Gill One of life's little pleasures is to act this out with children. There is also a genius YouTube video. You're welcome! People still sing this song to me from when I did it at storytime in July of 2009. This one I have on an iPod playlist. I made puppets using paint stirrers from the hardware store and coloring pages of people in different occupations.
Pete the Cat by Eric Litwin Don't forget to download the song. Would also make a wonderful felt board story. This is another iPod book.
Punk Farm and Punk Farm on Tour by Jarrett Krosoczka You can download the songs at punkfarm.com. Two more iPod books.
Seals on the Bus by Lenny Hort. Ditto.
