My students love to Zentangle! This lesson has always been a great success!
This is my two-page printable art lesson and assignment on the concept of "Zentangle". It includes a brief description and history of the art form to discuss with students, full directions for an art project where students will create a "zentangle tile", step by step instructions for students to follow, and plenty of examples and inspiration.
I have used this project as a collaboration piece where all of my classes create a 5"x5" tile and we hang them all together to create a "zenatngle quilt", but you can also do it individually and on a larger scale for more of a challenge.
This also makes a good sub lesson!
