It was such a privilege to teach for NewCAJE this year, the Jewish educators' conference. Here is an article that I wrote for their journal that is titled "Creating Tashlich through a New Games and Environmental Perspective" [2]with lots of background resource material as well as many activities and stories for community and family Tashlich time.
