This is a super easy game that I am sure many of us played when we were younger. Here's what to do in case you aren't familiar with it.
Take an object and hide it, when the "Seeker" closes their eyes or leaves the room. When they open their eyes, have them search for the object, while you tell them if the are "hot", "warm", or "cold". Hot means that you are very close to the object, warm means you are getting closer, and cold me that you are not close to it. Make sure that you take turns and allow the kids the change to give the directions as well.
Have you played this game? How did it work with different ages?
