You will need a map or and atlas. Choose a place name from the map and challenge your friend/parent to see if they can find it within a couple of minutes.
If they manage it, they choose the next place.. If they don’t find it show them on the map and choose another place for them to find.
You may be surprised to find some of the names of small villages.
This is a good game to play in the car to help make the time pass on a long journey.
