This is a lesson plan I made for my middle school students, but this can be transformed to work for elementary, middle or high school students.
I combined drawing skills with the art of Zentangle, animals, and the use of sharpie, pen and markers. This also utilizes the idea of positive and negative space and reflections.
If you preview the product, that is what the end result will look like. I included step by step directions with photos in the powerpoint to help you teach to your students as well as the ability to create your own.
