The first project my high school students do in Intro to Visual Arts is to design their sketchbook cover using Zentangle patterns (this can also be done on cardstock or drawing paper). This unit gives the students confidence in their drawing abilities and teaches them that art can be therapeutic.
This resource is a 73 slide powerpoint file that includes the daily slideshows that I use to teach my students over the course of the 8 lessons in the unit. The powerpoint file can be edited to suit your needs! (Please look at my store for a free download of the unit outline). This file coordinates with a file in my shop that includes all handouts for the unit.
I teach this unit to a class that is mixed grade (9th-12th) but it could be adapted for middle school as well.
