Get the box of chalk out and start drawing on the sidewalk with the kids. You don’t have to be a great artist to do this one. The kids sure won’t care. You can always sweep it away if you don’t like how your work turned out.
If you’re in an area without sidewalks, you may have a driveway or walkway up to your home that can be used.
You could also just try drawing a game on the ground. Kids love hopscotch, and what’s more classic than a chalk hopscotch game?
