Self-Esteem booster group activity: Have one girl sit on a chair in front of a white board while the others write positive phrases about them. They cannot peek at what is being written. Take a picture and give it to them.
Love this idea as a quicker/easy craft. Predraw the stem of the tree and then let each person add their flowers/leaves using the sofa bottle. Also a neat art alternative for those unable to hold a paintbrush.
