Update at 1414 Central Time: The administration at Guyer has provided further clarification on the textbook as used in their class. Here is their clarification:The main history book utilized in the Advanced Placement U.S. History classes for juniors in Denton ISD is titled: American Pageant. This is a history book that has had a strong reputation for historical facts for many years. The American Pageant, the official textbook, gives the exact Bill of Rights.The book in question, U.S. History: Preparing for Advanced Placement Exams, is a supplemental instructional aid and not the official textbook for any history classes. In this supplement, it states  above the amendments  that the following is a summary statement. The teachers and staff are aware of this summary statement and are teaching the amendments from the classroom textbook, American Pageant.The only approved textbook for these classes is American Pageant. All other materials are supplemental. Please be assured that Denton ISD history teachers are disseminating the correct information on the Second Amendment.
