I recently bought a Hugg-A-Planet. It's a giant stuffed earth. We had so much fun in yoga class with it. It was so inspiring to see each child hug it- it's like each child could grow up to save our hurting earth... It made me feel better that the world is in these fresh new hands.

We also read Whole World and acted out the song with yoga poses. This book by Chris Corr and Fred Penner has great pictures and changes the emphasis from the traditional religious song of "He's got the whole world" to "We've got the whole world in our hands." This makes it more appropriate for a public school setting. A wonderful book for empowering children to take action and change the world. This book also has a CD so you can easily act out the song with yoga poses.
