Screencast-o-Matic is a program that lets you record videos and take screen shots. You can add captions, overlays and more features if you purchase the Deluxe version, which is very reasonable for educators (as of writing this, it's $1/month if you pay for the 36-month plan). You can also turn your slideshow presentations into a video, post to YouTube, to Screencast-o-Matic's space or download to your computer. I highly recommend this versatile program. Stay tuned for a comparison to Screencastify, which is also excellent, but doesn't do captions.
Go to https://screencast-o-matic.com/ and register. You can use the free account or upgrade.
