Screwdriver Sketches

You may not initially be impressed by this sketch but, trust me, you should be. This work of art was created by an 8 year old girl. It's true, it's not perfect, she still has a lot to learn but considering that she's 8 there's a lot of promise contained in this sketch. The original sketch is a Christmas gift for someone so I won't get to keep it like I do most of her other pieces so it had to be scanned in for posterity's sake- and so I could brag. The image below is of the same screwdriver sketch about 3 months ago (when she was 7 and it's not a very good scan, sorry) and is just to show some comparison of her developing skills. Ophelia tends to be drawn to the every day things, items she can focus on in one sitting. If it's too big or too detailed she'll become overwhelmed. Something about the screwdriver drew her back to try it again, I'm not sure what but she mentioned how she liked the contrast in how the light reflected off the metal and but there are also some dark areas of deep shading. Anyway, I think it's a beautiful screwdriver. It took her about 10 min. to begin and complete the new sketch, I don't remember how long for the older one.

Any of you artists out there that can give me some advice on how to encourage her without pushing her (I've seen stage parents, I imagine the same thing is possible in art and I don't want to do that) would be much appreciate. I'd love to know what kind of supplies she should have available, how often we should encourage her to draw, what other mediums she should try, etc. Are art classes appropriate at this age? She did participate in an art program after school last year but she hated it and they never seemed to do anything useful (it didn't seem like real instruction, just arts and crafts "art projects") so I didn't push it. Any other (really cheap) ideas you have would be great. Thanks!
