Each grandchild gets to take a trip alone with their grandmother to a foreign country. In this book they travel to Mexico where they get to see ancient pyramids - deserted a long time ago, see a volcano, go to Frida Kahlo's house, watch folk dancers, and eat Mexican food. They also see ball courts where the first team sport began, go to the zoo, and more. Grandma thinks this is the fun way to teach the children about other people and cultures and have fun at the same time. The book is loaded with photos so the reader can see the sites along with them.
