We used this book as part of our homeschool curriculum (Sonlight). It has some good information in it that was able to promote good conversation, but I feel like there wasn't anything specific that we will remember from reading it. It's good to show how different people around the world live, but I find that it was more useful when I supplemented additional information about the things we were reading.
Another Usborne book that we enjoyed. Full of information on peoples and cultures around the world, people's language, money, food, homes, religions, holidays, music. . .
We used it as an overall introduction to the idea that people around the world are different and diverse before we go into a world history study where we will be in depth in specific cultures. I think it achieved the goal of a great overview and can be pulled out as a reference when necessary.
