The image shows a classroom with a green table in the center. On the table, there is a stack of wooden blocks arranged in a way that they form a bridge-like structure. The blocks are of different sizes and colors, and some are stacked on top of each other. There is also a black book on the table with an orange design on it. In the background, there are other tables and chairs, and a bulletin board on the wall. The floor is tiled, and there are bookshelves on the right side of the image.
