For my final unit at the elementary school I focused on the Op Art movement with most of the grade levels. Here are some of the examples of what the students accomplished.
4th grade looked at artworks by Bridget Riley and Victor Vasarely. They learned about illusion in making their cone shapes appear like they are 3-dimensional. They practiced creating value with color sticks.
3rd grade worked on something similar, creating an illusion of fabric. They learned how to blend with oil pastels and to create highlights.
The 6th graders also looked at famous Op Art artists and practiced their weaving skills to create these neat looking pieces.
For the exceptional education students we did some printmaking using the Op Art texture sheets. The students loved layering prints over each other to create new illusions.
