This one was fun. We made a little puzzle out of one of Little Boy's drawings.
I gave him some cardstock, markers, and stickers, and told him to draw whatever he wanted. So he drew...a ball. I suggested that maybe he'd like to, y'know, color it in. A bunch of white space = not a fun puzzle.
Anyway, then he stuck stickers all over the paper, and I cut it into biggish puzzle pieces. He was really excited about putting it together.
After trying it once, though, he said that it was "too tricky" to get the pieces to fit together. Meaning, the pieces slid around too much. We'll try it again another time, I guess.
