The image shows a classroom with a group of children sitting at their desks. The desks are arranged in rows and the children are wearing green t-shirts. The boy in the foreground is holding a piece of paper and appears to be working on a math problem. He is looking down at the paper with a focused expression on his face. There are two green trays on the desks in front of him, one with a ruler and the other with a pencil. The children in the background are also working on their math problems. The room is well-lit with natural light coming in from the windows on the left side of the image.
