I bought a couple of new books after seeing The Artist Who Painted a Blue Horse by Eric Carle on another art teacher's blog. Amazon is wonderful! It suggested another book, Swirl by Swirl; Spirals in Nature by Joyce Sidman, which of course I purchased also. The next day my books were on my front porch (2 day prime shipping is the best!) I can not wait to incorporate these into some lessons. I am including the link to amazon so you can find them.
