Scholaric supports embedding youtube videos in your printout page. By embedding a YouTube video, I mean that the video itself...
...rather than a link...
...appears in the page when displayed on screen (not in a printout). This keeps the student on Scholaric's site, and not on YouTube, which can be a distraction, with all its related video suggestions.
To embed a YouTube video, first visit a YouTube video page, such as this math video
Next, click the share link below the video.
And there you have it.
