"The Constitution of the United States: An Introduction" by Floyd G. Cullop was a book designed and written to serve a young adult audience or more specifically, students in grades 8 through 12. Floyd Cullop spent many years as a history teacher and has written a number of historically related works. As a history teacher Cullop encountered many students who had difficulty reading and understanding the Constitution of the United States and therefore decided to present the document in its entirety, along with clearly stated definitions and explanations of the text and what it means. By doing this Cullop is able to give students the opportunity to read and understand one of the most important historical documents in United States history, as well as the contract that outlines the rules and regulations of government that affect the daily lives of every citizen in the nation.

Cullop does an excellent job of explaining the text in an abbreviated manner so that is easily understandable, but significantly more interesting than a simple list of names and dates and rules.

Cullop breaks down the work into 6 parts:

Part I: Introduction to the Constitution, defines constitutional government, details the historical background of the Constitution and its predecessor, the articles of Confederation and perpetual union, and is finished with a list of fill in the blank questions and a list of important words and terms.

Part II: The Constitution Explained begins by dissecting and explaining the Preamble. Cullop was very clever in the design of this particular section in that he placed a quiz and a list of vocabulary words at the end of each article so that the student may not be overwhelmed by all of the information contained in the entire chapter and document. There are also sections throughout this part that name alternate resources for important information not actually listed in the text of the Constitution.

Part III: The Bill of Rights defines the Bill of Rights and contains an explanation of same. The Bill of Rights is probably the most famous part of the Constitution.

Part IV: Amendments Since the Bill of Rights defines and lists the constitutional amendments, from prohibition to the end of slavery to income taxed to the voting rights of women and blacks.

Part V: The Constitution of the United States contains the entire text of the Constitution of the United States in the manner in which it was written.

Part VI: Know Your Qs and As is a list of 203 questions and answers pertaining to the text of the Constitution, its background and historical importance.
