Teacher Tips

At the time this Learning Resource was published, the COVID-19 global pandemic was impacting schools and communities around the world. Keeping this in mind, the team at New American History embedded language in the body of the text to help adapt to a variety of educational settings, including remote learning environments, face to face instruction and blended learning.

The topic of 9/11 can trigger difficult memories among many students and their family members.  Be considerate of this when asking students to conduct interviews with their family or other trusted adults. Students who are Muslim Americans may be equally concerned with how this topic is discussed and taught. This blog post from Critical Connections is a useful tool for educators preparing to discuss 9/11 as well as other social, political, and religious trends related to Muslims in the U.S. and around the world.

If you are teaching remotely, consider using videoconferencing to provide opportunities for students to work in partners or small groups. Digital tools such as Padlet or Jamboard may also be used for collaboration. Rewordify helps make a complex text more accessible for those reading at a lower Lexile level while still providing a greater depth of knowledge.

This Learning Resource includes the use of a student Reflective Journal. Additional resources for using Reflective Journals remotely may be found at Facing History and Ourselves. You may want to read this NYT visualization for more background knowledge on how 9/11 is taught from a global perspective.

These Learning Resources follow a variation of the 5Es instructional model, and each section may be taught as a separate learning experience, or as part of a sequence of learning experiences. We provide each of our Learning Resources in multiple formats, including web-based and as an editable Google Doc for educators to teach and adapt selected learning experiences as they best suit the needs of your students and local curriculum. You may also wish to embed or remix them into a playlist for students working remotely or independently. 


What should Americans know about September 11, 2001?

On September 11, 2001, terrorists attacked two American cities using hijacked commercial aircraft as weapons.  They flew airplanes into each of the Twin Towers, the two tallest buildings in the World Trade Center, a business complex in New York City.  Another plane flew into the side of the Pentagon building in northern Virginia which serves as the headquarters for the U.S. Department of Defense.  An additional attack on a target in Washington, D.C. was thwarted by the passengers of United Airlines flight 93 who fought the hijackers for control of the plane before crashing into a field in Pennsylvania.  Nearly 3000 people were killed, including all of those aboard the four planes and many of those in the buildings that were hit.  This attack shocked the world and left a lasting impact on America.

As you watch the video from CNN and learn more about the events of September 11, 2001, record your thoughts, observations, and reactions in the 9/11 Reflective Journal.  Once you are finished, turn and talk with a partner to discuss your responses. If working online, your teacher may allow you to use a Padlet, Jamboard, or another collaborative tool to share your responses digitally.

Next, examine this collection of 9/11 Response Art located at the 9/11 Memorial and Museum.  Choose one that speaks to you and complete the final portion of your reflective journal, sharing the type and name of the artwork, as well as the impact this piece had on you.

If working remotely, your teacher may provide opportunities to collaborate with classmates using video conferencing, access to an online chat feature, or breakout rooms.

Your teacher may ask you to submit your reflective journal or record your answers on an exit ticket. 


How does perspective influence the recording of historic events?

Perspective is the viewpoint of those who have witnessed an historical event. Historians use many perspectives to determine the elements of an historical event, its causes, and its effects. Historians often use interviews or oral histories to provide a more accurate recording of history by including multiple perspectives.  There will be as many interpretations of an event as there are witnesses.   

Imagine you are planning a presentation or exhibit on the events of September 11, 2001.  Whose voices need to be included in order to provide a full account of the event?

Create a list of the types of people you would want to interview to include in a presentation.  Consider the varied locations, professions, and vantage points of people who were there that day.  Also, consider people who were not in the targeted areas, but who might have witnessed the events via technology.  What perspectives could they offer?

Next, sort those people into categories.  What are the main groups of individuals who could provide the details of the attacks? 

Turn and talk with a neighbor to compare your groups or, if working remotely, your teacher may provide opportunities to collaborate with classmates using video conferencing, access to an online chat feature, or breakout rooms.  Are there any additional groups or individuals you need to add to your interview list?

Next, choose one of the oral histories of September 11 as recorded by Story Corps and take the following steps:

As you listen, create a list of questions that prompt and support the answers you are hearing.

What additional questions would you ask? 

What additional information do you want to know?

Your teacher may ask you to record your answers on an exit ticket. 


How do different perspectives impact the collective memory of historical events?

Compare and contrast the experiences of three witnesses of the 9/11 attacks by listening to oral histories from the collection compiled at the National September 11 Memorial and Museum.  You can also click on the transcript option if you prefer to read their stories.  Use the 9/11 Collective Memory Graphic Organizer to help organize your thoughts. 

  • Begin with the oral history of Frank Razzano and complete the graphic organizer as you listen to his story.  
  • Then select two other witnesses from this site and add details about their experiences to your graphic organizer.
  • Summarize the similarities and differences between these witnesses at the bottom of the graphic organizer.

While eyewitness accounts can be a valuable resource to historians, they are not always complete.  Sometimes emotions can impede an accurate description of events.  Often witnesses only experience a portion of an event so they can provide only a partial description.  Therefore, historians have to seek numerous sources in order to determine an accurate account of an event.   

What information do you still want to know from these witnesses?  

You may want to conduct your own interview with a family member, teacher, or other trusted adult who experienced the events of 9/11 either from a personal connection or as an observer, watching events unfold that morning on television, radio, or online.  You can complete the final column with your graphic organizer to include their information.

Your teacher may ask you to submit your graphic organizer.

Your teacher may ask you to submit your graphic organizer or record your answers on an exit ticket. 


How should America commemorate the events of 9/11?

As a community decides to commemorate an event with either a monument or museum, many considerations must be made.  How should the event be portrayed?  Which perspectives should be included?  What artifacts or visual representations should be selected?  These elements have a great impact on how that event will be remembered.  

Read the excerpt of “9/11 and the Inevitability of Forgetting” on Bunk about how time can begin to erode the details of historic events from people’s memories. Take a few minutes to explore other Connections on Bunk using the "View Connections" button or by selecting an icon next to the stack of cards with related content. You may explore further using the full collection in this Bunk Exhibit.

If you were the designer of a museum that commemorates the events of 9/11, what elements do you feel are needed to honor those who were impacted by the events of that day?  Consider visuals, oral histories, artifacts, art, music, etc.   What elements would best capture the events so that future generations can understand the impact 9/11 had on America? 

  • In a collaborative document such as a Google Doc, Google Slides or other platform supported by your school, create a list of ten of these elements.  
  • Next, visit the 9/11 museum online.
  • Create a visual “collection” of the items that meet your requirements, by pasting them into your document.   
  • You may see something that was not on your initial list, and you can add it if you like.

Once your collection is complete, reflect on the following prompts:

  • What do you think is the most thought-provoking element you chose?
  • What is the most inspiring?
  • What is the most surprising?
  • What is missing?

You may also want to look at the memorial sites for the Pentagon and Flight 93 for more perspectives.

Your teacher may ask you to submit your collection and reflection or record your answers on an exit ticket. 


Does America need to revisit its commemoration of other key events in U.S. history?

Search the topic of collective memory on Bunk and select another historical event.

  • How has this event been acknowledged?
  • In what ways has this event been commemorated?
  • Which perspectives have been included?
  • Which perspectives have been left out?
  • What additions or changes might be made to give a more complete account?

Examples of events might include Juneteenth, Civil War statues, the 1918 flu pandemic, World War II, or the arrival of African American to the Virginia colony in 1619.  

Finally, you can compose a letter to your local government officials or editor of your local newspaper to propose a way to commemorate the event you chose.  

Your teacher may ask you to record your answers on an exit ticket.
