While reading one of "The Magic School Bus" books the other night, Berit pointed to a picture of an open door and asked me how the illustrator drew it so that it looked open. So we got out some paper and pens and launched into a fun lesson on perspective. Examples I used included (but were not limited to) the old "Kids in the Hall" routine where you squeeze the other person's head with your thumb and forefinger. Berit dug it, though, and she did a pretty good job with the whole perspective thing. It lasted a few minutes before we moved on to writing "bubble letters."
