I particularly like the avatars where there were no facial features. Each identity was described by the hair, clothes and accessories. What if students did the same thing? Each of those things is a choice we make based on our identity; what we prefer and what we want others to know about us. Many of these choices come from our culture and the groups we belong to. The lesson could get really interesting if students had to trace their choices to something in their culture. This would be a fun extension!
What I've come up with, however, is a lesson packet that will have students learn about the concept of "Identity" through a presentation. There is a formative assessment where students will write a few things about their identity. The teacher can assess that they understood the presentation and class discussion about identity. The teacher can also assess that they have a few ideas for their avatar drawing.
Next students will write a mission statement. The mission statement can be about school or life. There is also a "work" mission statement writing sheet in case you or colleagues want to try this.
They will write their name at the top of the page with BOLD letters. I've included a guide to help them out with that.
Then they will draw their avatar using the Avatar Gal and Avatar Guy drawing sheets.
If you like the idea of making the avatar on a square and displaying a grade level or school's avatar's together, you could use a square paper instead of the sheet I provided, or you could make the sheet included in the lesson the practice drawing and have the final drawing on a square paper that gets displayed with the others.
