most others are added to the common boxes, which are sorted by rough shape based on what we’ve seen stimulates free building.
I inherited a bunch of legos from older cousins when I was a kid (and I've since donated them to a school). My parents did get me a tackle box to go along with them, and sorting/putting them away is as much part of the play/learning as building, I think. Just like you can't really go fishing if you can't find the right lure, you can't really build that spaceship if you don't know where the cone piece is.
