I don't think you're ready for these jellies

First grade rocked their jellyfish paintings.

I had intended for this to be a one day lesson, but after thinking of the various steps and uncovering a Mark Kistler DVD I made some changes. On the first day we talked about watercolor paint, transparency and I demonstrated how to do a wash. They were given the blue liquid watercolors and a mop brush. I had them paint their backgrounds only - which took all of 5 minutes. While the backgrounds dried on their table, I fired up the DVD which had a segment on drawing jellyfish. They got very good at drawing the shape.
For the second week, I demonstrated how to paint the jellyfish, including the forced air tentacles. They used the rest of the time to paint. It's a much better result than if we'd done it all in one class.
