I focus on just using stuff with my kids. Things like piloting a remote control car is hard for a 4 year old, but they still want to do it. Playing Tetris on a slow speed, naughts and crosses, simplified chess, making objects out of paper, painting acorns, building train tracks, Lego, and so on.

You need engagement first, in order to cause learning, and I guess any process that causes both learning and engagement makes sense, but in my experience at young ages, that's more likely to be on the doing/using rather than creating side of the spectrum.
