Hi L.
The Berenstain Bears Think of Those in Need is a good book.
My 5 yo and I just finished helping at a blight busters/art works location in Old Redford where we built a temple. Sort of a fancy gazebo, planted trees, flowers, and also helped in the kitchen to feed the other volunteers. She did a really good job, and we did get some work done too. We talked about what a community was, and the good work being done while we worked.
We also have a secret mission to spread joy. When we go out into the world we smile at people and wave, do small things to help. I found this had a really big positive effect on our attitudes. You can't spread joy if your grumpy.
Good luck :) A. H
