My Take
I think it is a really cute and informative way to introduce students to different coding languages and coding in a very simple and easy to learn manner. Whether they want to code art, music, or a simple creative game, Pencil Code allows them to do so. In my experience I was able to code a simple line of music with multiple instruments with little knowledge of coding!
How I Use It
I would use this resource to introduce students to the basics of coding and coding languages.
