doubtfulguest, are you kidding me? I can't believe a 5-year old can even do that! Awesome! I think you may be right about her math ability showing through the drawings. I say this because I consider DD4 to be quite creative and artistic. She has done the negative drawings that Nautigal mentions without ever learning it from anyplace. Kind of similar to how your dd self-taught perspective drawings. But my dd's drawings are not precise, like your dd's are. Your dd could grow up to be an amazing engineer!
