The New York Times has published a perfect interactive to use in a lesson on the Confederate Statue controversy (see The Best Resources For Teaching About Confederate Monuments).
The Times interactive is titled “Which Statues Need To Come Down? You Decide.”
It shows statues of many historical figures (ranging from Christopher Columbus to George Washington), includes a short summary of the controversial issues surrounding each one, and then asks you to vote. At the bottom of the page, you can see the vote totals for all the statues.
Projecting this on the board and having students vote could be an excellent part of a lesson on the topic.
