It’s easy. Just write down a list of 100 things you might see along the way, like landmarks, buses or bridges. The first person to complete the list wins.
For preschool kids, substitute magazine photos and trim the list to twenty familiar objects. For older kids, include a challenge: require them to provide one additional fact about each item they find.
Have fun. And by the time you reach the end of the road, you won’t be at the end of your rope.
