This PowerPoint presentation has my notes on the causes and weapons of World War One. Back in the day, I used to make students copy them from the board :) These have been updated so they are interactive with links to videos, games, and primary sources and they also seek student input throughout the lesson.
Please email me at email@example.com after your purchase so I can share the Google Slides version of this activity. Many of the features will not work in PowerPoint format. Once you have the Google Slides presentation the activity will be editable for your needs.
Thanks so much!
