In response to the events of September 11, 2001, author Kathy Martin has answered the question that many children may have, What Do Those Two Numbers Mean? Although most children have frequently heard “9/11,” they may not know what happened on that horrible day or what those two numbers really mean. While using dialogue between a young boy and his mother, Kathy has creatively explained the importance and significance of those two numbers to Americans today. She delicately approached the subject matter in order to remain true to the events while, at the same time, appropriately educating young readers. Parents and educators can effectively use this book as a resource in helping to explain and answer, What Do Those Two Numbers Mean?
