About 5 weeks ago when I started Little Bean on Kindergarten work I put a 24 piece puzzle into one of his work alone boxes. To my surprise (we had not done many puzzles up until this point), he finished it within minutes, and was SO proud of himself. Since it seemed to be an activity of great interest to him, I began rotating our few puzzles through his boxes each week.
Then, a few weeks back, I took them to the dollar store and purchased two 50 piece puzzles (just because that was what they had). I wasn't sure if that would be too many pieces for him, but alas it wasn't. He spent the better part of an hour working on one 50 pc puzzle, but completed it without help, and with great interest and enthusiasm (read: "Mom, look how good I'm doing! You have to come and see!").
Here, he is completing a 100 piece puzzle I purchased at Toys R Us for only $1.48. This kid is INTO puzzles! In this instance, Little Bean spent about 45 minutes putting this together only to immediately take it apart again and proceed to rebuild it. :) I'm totally excited about this new, quiet hobby he has taken up!
