Educational Music video about shapes

And I also remember that the voice actor was in a energetic, amarican accent. (Not saying that the music video is created in the U.S., but it might be from here.)
There is another scene about the circle, but I can't remember what it exactly was it about. And thinking about my last post, it might be 16:9 because I possibly remember being black bars at the top and the bottom. (I was watching this with an iPad btw.)

Wydm? I remember wwtching this on youtube.

Why not look for the video? I am pretty sure this isn't lost. (and also, read this thread if you are interested in finding it)

I don't remember the channel's name. Practically everything I posted is the only thing I can remember so keep that in mind.

Did you read my first post? I said that I saw it somewhere between 2014-2016. And maybe you should tell other Lost Media Youtubers about this thread (for example, Shaiivalley and All Things Lost), that should help spreading awareness.
