We recently read the story "Rainbow Fish" and it's also avaliable on the best website ever: http://www.storylineonline.net/
Anyway, the kids created a fish...we echoed the steps together and they outlined the fish with a variety of colors using crayons. Then we painted them using liquid watercolors...the colors are so great. Then, to tie it in with the story, we added one shining silvery scale because the rainbow fish was only truly happy when he shared his beautiful scales with his friends.
It was a lot of fun!
