The book is based on Genesis 11:1-9 in the Bible. It introduces the reader to the Tower of Babel and provides a brief explanation as to how we got our various people groups.
Although it is advertised for ages 4-8, I recommend reading it as part of a family Bible study before reading the actual account in the Bible. The vocabulary and subject matter is too difficult for most four to eight year olds to grasp on their own. On the other hand, your older children will probably want more explanation than is given in this book.
As an introduction to this passage of scripture, The Tower of Babel does a great job. The beautiful color illustrations and fun pop-up Tower of Babel will keep your children’s interest as you read and discuss the text together.
For a more detailed Biblical explanation of the Tower of Babel and our various people groups, I recommend the Answers In Genesis Web site.
