I have started a wall timeline for the kids. So far, it's pretty boring. A long line on the wall, with creation written at the beginning.
I guess Z wanted to make his own because I found him working very hard on this in the office this afternoon:
The world is at the beginning, and then the stick figures are as follows from left to right: Noah, noah's boat, Moses, David and Goliath. Cute!! (he told me he though that he was drawing Goliath first, and then david, but when he looked at them the second guy looked mean, so he is goliath.)
