I remember in kindergarten gluing a thousand cotton balls on a paper cutout of a bunny for Easter. That activity, although I enjoyed it, wasn't very creative.
I think art lessons in preschool lesson plans shouldn't be something that the teacher does and then the kid colors it. I know why teachers do this. They want a nice finished product for parents. They know that their child didn't do that complex cut and paste job. So why don't we, as teachers focus on the process, and not the product. And teach parents the same concept- that it's the actual act of making art, not the final product, that matters.
We can work it in our themes. An example would be having paper cut into butterfly shapes and have them paint with watercolors. Stamp painting with kitchen implements, car painting, or sculpting with clay would be other suggestions. They are still the creators.
I think if we can teach our children to be creative thinkers, to think outside the box, then they will be better at so many things when they grow into adulthood.
