I forgot to make this one! For completeness, it is logically essential. But here's what's interesting: this idea is never a problem nor a hang-up for anybody! Why not? It's maybe the same reason I forgot to make the video: this is somehow a super-duper intuitive concept. Intuitive means natural. We people just seem to naturally know that there are objects around us, they are separate objects, that they can be globbed (or "considered together") into groups, and that we can count up how many single objects are in a group. Which is really a whole bunch of ideas! And what's more: these are ideas that would be very challenging to teach. Can you imagine trying to verbally teach them to someone who did not already naturally understand? Where would you even start?
Blessedly, we seem to naturally understand all of this. So we don't have to ever truly "teach" the idea of HOW MANY? from scratch. Good, because that might be tough! But what we can do is make sure that our understanding sound, simple, and... really just perfect, about this idea (or this group of ideas).
So we do.
