A group of young people wearing maroon skirts and maroon hooded sweatshirts, possibly uniforms, are gathered on a grassy lawn. They are working on a grid-like pattern marked out on the grass with string. Some of them are kneeling or crouching down, using tools that may be rulers or sticks, seemingly taking measurements or adjusting the string. They are also holding notebooks or clipboards with papers, perhaps recording information. The scene suggests a school activity or outdoor lesson, likely involving geometry or a similar practical exercise.
