Create an image featuring a friendly teacher in a cozy classroom setting. The teacher, a woman with shoulder-length hair, wears a long cardigan and holds a pointer while engaging with three cheerful children. The children, one boy and two girls, stand next to her. The boy has short hair and wears a pink shirt with denim shorts. One girl has curly hair with a striped blue shirt and a skirt, while the other girl has straight hair and a pink backpack. The classroom is decorated with colorful drawings, a wooden desk with books, and a green chalkboard with simple math equations instead of music notes. A clock is visible on the wall, and sunlight streams in through a window, brightening the space.
