During my classes we made large 2D paper collage lanterns. We combined metallic, translucent, and construction papers. And we looked at several festive images of Deepavali celebrations from all over the world.
Here is my 2nd grade class displaying their lanterns (some finished, some not-so-finished). And below, two of my 4th graders who came to visit during lunch. Everyone was so brightly colored and cheerful today!
