As I often do, I led them step by step through the process of seeing their animal. Since the class was small, each had a large plastic model to use.
One helpful hint is to start with the eye. The eye is one detail that encourages the artist to draw a larger picture. Here is the model I worked from.
Below it is the sketch I drew as I talked.
I am not as concerned about drawing a really good lion from the model as I am about encouraging the children to look hard at their models. As it turned out, I made the muzzle much too long so that was a good opportunity for me to show the children how a drawing can be corrected if it is drawn in markers.
I also see that the legs are too long. However, the legs are fine for explaining how to keep front and back legs the same length by drawing a line of tiny dots across the page. We talked about where the back side legs seemed to be when we looked at the models even though our brains knew they were on the same level as the front legs. This was a good opportunity to discuss how things appear differently when they are farther away.
There wasn't anything I could easily do about drawing the body longer but we talked about the fact that it was too short.
Here are the children's drawings and the models they drew from.
