This is a step-by-step handout that teaches students how to create a Notan heart project.
We did ours with 6'' x 6'' white squares and colored post-it notes!
The students can create cards or artwork!
This would be a great lesson on symmetry and is suitable for an elementary or art classroom. It would also make a great sub plan!
