Solution Videos allowed on YouTube?

I’m not sure this is allowed or not so I wanted to check first. I was teaching unit 3 last spring during our at home learning. The students were struggling with it because for many, coding is very new. To solve this, I recorded videos of me solving all the lesson bubbles for unit 3. I am interested in using those videos this year to help my students, but I’m not sure I should put them on YouTube as unlisted videos. Can someone from let me know if this is a problem? If it is, I’ll take them down, but YouTube is the easiest way to distribute them.
