tweening?

So how do I tween object movements? I want to move all children in a certain GO a certain amount to a certain direction over a certain timespan while another certain GO moves a different certain amount to a certain other direction over the same certain timespan. If anyone knows anything/has any useful script asset for this, I’d gladly receive it here. Certainly.

This is very comprehensive:
