Find a large driveway, sidewalk, or protected concrete area.
Step2
Take your sidewalk chalk and begin drawing scenes that can contribute to an adventure.
Step3
Can start by drawing a desert island, then some water, and a deserted port city. Create additional steps along the way to the final destination, like your child's house.
Step4
Then take your child through the steps of the adventure, describing each location along the way, and asking how you are going to make it to the next step.
Tips & Warnings
Use as many descriptive adjectives as you can, make it feel like an adventure, and get into it yourself. Your child will want to play over and over.
