A scavenger hunt is a classic activity! It is simple and fun for anyone, and you can use anything as an object to be found! The fun is in the chase. In the spirit of the holiday season and Ney Year during which this post was written, try hiding holiday decorations for residents to find and then put them away as a fun spin on things.
To create a successful scavenger hunt in which all participants will feel rewarded, try making a string of clues for each participant to follow around the community until they find the item they're hunting for! Even modifying the difficulty in finding the clues is a way to adapt this activity to different residents to assure everyone enjoys participating! This way, you can have one participant in the scavenger hunt at a time, chasing their own clues. Once the resident has finished their adventure, the environment can be cleaned and staged with new clues for a new resident!
Having multiple solo hunts organized sequentially like this enables the activity to become a sort of group activity when needed. It can also be easily used as a one on one activity! Have fun with this idea! :)
