Misty, have they been narrating the pictures? I don’t do it with *every* one, but several times in a study I have the kids narrate the picture to me in some way–they describe it, or try their hand at sketching it out. When they were small, they LOVED to “describe” it to me while I tried to reproduce what they described–that really made them aware of what they were saying! Plus they got to laugh at Mommy’s pitiful drawing.
One other suggestion–do you enjoy art? If not, try taking a “mommy culture” thing and find a good library book on the subject and educate yourself. Art, music, and poetry are really areas where Mother’s enthusiasm is catching–or her lack thereof is not. If you don’t love the subject yet, find out more until it is more interesting to you.
I really like the Discovering the Great Artists book, it has projects that make each artist fun. There are also a few free coloring pages of a few artists available online, and Dover has coloring books available. My kids weren’t big “colorers” but they did like those.
One year I had prints instead of just using books or a computer, and I “auctioned” off the prints to the kids after the year was over for little chores or favors, and they got to put their favorites in their room.
Also we loved the book Art Fraud Detective; it really got the kids looking for little details and “signatures” of the different artists.
