Hi. handprint sharing can be fun, if a little messy :) Have dishes of ready mix paint on the table & invite the children to dip their palms into them. Share the painty hand/s with someone elses - palm to palm. Then see what colours print out onto a sheet of paper. Write 'I shared my hand with xx' on the individual sheets to promote the cooperation and collaboration aspects of friendship.
Alternatively you can use storybooks to promote PSED there are
categories for that here,
Side by Side is cute. Use the observations you have to see who she tends to gravitate towards, what they do together and how you can use those interests to grow her friendship circle.
If it helps there's an
activity planner on this thread
