Corin and Legos is like Ryanne with books. Both are far beyond their age levels, ability wise.
Corin has had a few sets for 4 & 5 year olds. He typically finishes them under an hour. He's currently working on one that's 7+ and it's taken him 1.5 hours with probably another 30 minutes to go and has been a totally independent process. The 9+ set he worked on took him a couple of days, but he also made some substantial errors. (Fixed by mom and dad, but they did keep him from progressing and required some maneuvering by us to fix.)
I haven't been able to figure out if it's sheer number of pieces that makes it take longer or if it's actual building difficulty. Pieces definitely makes for a longer process, but there's some correlation by Lego to piece counts and age range as well and I don't totally understand that.
Books are easy. Raw page limits are the answer for now. This Lego thing is going to take some work.
