This morning I answered an email from a reader who was looking for a suggestion for a timeline creation tool. My recommendation was to try Timeline JS which is my favorite tool and is featured in my Teaching History With Technology course. But there are many other ways to create timelines. Two of those ways are hidden in the tools that many of us use on a regular basis. Google Slides and PowerPoint have templates for making timelines.
Browse through Microsoft's templates gallery and you will find an entire section devoted to making timelines in PowerPoint and in Word. I really like this circle accent timeline template.
Google Slides also has timeline templates that your students can use. In the following video I demonstrate how to access and use the timeline option in Google Slides.
