group of children in a classroom, seemingly engaging in some form of exercise or dance. They are wearing uniforms, mostly pink shirts and dark red dresses or trousers, with some individuals also wearing head coverings. The children are standing close together, and they are moving in unison, bending and swaying. There are books stacked on a desk in the foreground. The classroom appears to be simple, with a chalkboard on the wall and what looks like a brick or concrete construction. The lighting is natural, but the interior seems a bit dark.
