This is a classic activity that entertains kids of all ages! I'm always amazed that the simplest of activities are always the most fun for my daycare crew.
Here's what we did:
1. Hunt for the perfect rock outside.
2. Paint your new pet rock. We used washable paints.
3. Let dry.
4. Decorate. We used pom ball noses and googly eyes.
*You could also incorporate literacy activities by having older children write stories and journal entries about what they did with their pets. My Kindergartener made signs for his pet's home and wrote in his journal about his pet's day.
These little rocks kept them entertained ALL DAY LONG! It was wonderful :)
