Do you have some tech savvy residents in your community? Why not organize a group activity with them all about Emojis, to celebrate World Emoji Day!
You could print out photos of popular emojis and have them guess what they are? 
Or encourage them to text back and forth with one another using only emojis and see if they can figure out the message that's trying to be sent.

If you have residents who use Smartphones, Tablets or Ipads, but maybe don't use emojis, do a little workshop to teach them how to use them when they're sending messages to kids and grandkids.
