I think there may be many possible projects for a class that would like to adopt older folks from an assisted care community or residence.
A few ideas:
Get a list of everyone’s birthdays in the residence, have your students chart/graph this and make cards for birthdays.
Create surveys asking residents about favorite things, have your students write stories, poems, etc. based on the results of the survey.
Make cards, ornaments, placemats etc. as gifts for the holidays.
Create and send a student generated monthly newsletter, magazine, newspaper. Copy for each resident.
I also found this on Facebook:
International Card Exchange for the Elderly. It lists homes that are asking for cards. Some of them are overseas – great tie in with geography. *I am not sure how current this page is, I am trying to get more information about this.
