I painted a map of Vanuatu on my school! The big colored names are the provinces, the smaller names are the island names. As I was painting it, a 1st grader came up and asked me what country it is.
"What do you think?" I asked her. "Is it the U.S.?"
"Yes," she said firmly.
I laughed. "It's Vanuatu!"
"Oh. Which one is Australia?"
"None of them. It's just Vanuatu."
"But which one is Vanuatu?"
"They all are!"
"But which ONE?"
...I think this map will be useful here.
