The foundation in charge of raising money for the Sept. 11 memorial has launched a program to help teachers instruct students on the terrorist attacks.
The lesson plans include a video of survivors and witnesses recounting their memories of that day.
Joe Daniel, President of The National September 11th Memorial and Museum, says it's important for students to be able to discuss the day in an objective setting.
DANIEL: It is the job of the excellent teachers of the public schools in New York City to guide the actual lessons and to use what we are providing his video as the touchstone for those lessons.
REPORTER: The materials were introduced at the Millennium High School in Lower Manhattan. The foundation says its intent is to help students understand the differences between primary and secondary sources, how history is written, and how memorials play an important role in documenting the past.
