Second grade is the best! Look at how good they are...
In this lesson, I used a PowerPoint from Ms. Brown's website http://www.mrsbrownart.com/2nd.htm which helped the students learn what Op Art is all about. They also learned about Complementary colors - if you stare at one color for a long time, sometimes you will see the opposite of that color when you stare into a blank space. So hopefully when you stare at their pictures for long enough, the shapes will start to disappear!
