Every year around Lunar New Year, I bring my Chinese calligraphy materials to school so students can get a chance to write a couple characters. The characters range from spring to beauty to prosperity. Since I teach in a district that is predominantly Chinese, it is something that students are familiar with, but most students do not practice writing Chinese characters through the art of calligraphy. I would start by asking the students to take out their pencils and I would model how to hold the brush.
http://www.chine-culture.com/en/chinese-painting/material.php This is a basic website to show the materials and how to write Chinese calligraphy. If unable to write with those materials, thicker brushes can still work with black watercolor paint as it is the idea to hold the brush differently and write characters that some students aren't used to writing. It's a great way to show how different cultures incorporate language and writing.
