Op here. I’m sorry for not describing better. I’m actually really tired, so I don’t know if I have the energy to get into all scenarios.
I mean today, my 5 yo (he just turned 5 so I got it wrong above

picked up a puzzle. Dh gave him the option of picking up his puzzle OR his hot wheels tracks. Child picked the puzzle and did it.
But, that was rare. And it wasn’t me asking. I feel like they have tuned me out until they need something from me. But in general, I just need them to pitch in. And they don’t. Either ignore me and play wildly, or the 8yo seems to pitch a tantrum, or I offer a positive consequence (they get excited but do nothing to follow through).
I’d bag up their stuff, and maybe I will... but then again it almost seems like me doing all the work of picking up.
Then also, it’s not just toys, it’s a Tupperware dish they messed with, a backpack from an outing, shoes, a coloring page, a cup, a stray kids Christmas decoration, a roll of paper towels, books, a kitchen cloth, a pillow, etc.
