I agree with Val. My daughter, who is eleven now, loves to work jigsaw puzzles. I did teach her about the frame later (when there was one) and yes, mastering that puzzle seems to be the thing for them.

My daughter enjoys the struggle. She is a "take it apart" kind of girl. She loves to explore the inside of old computers and toasters and whatever she can. All of these are puzzles.

I am hoping she will begin working on our cars soon and save us some money.
