Which of the following skills is most related to fine motor development?

Fine motor development involves the coordination of small muscles, particularly in the hands and fingers, to perform tasks that require precision and control. Writing and buttoning shirts are both activities that demand intricate hand movements and dexterity.

When a child engages in writing, they utilize various fine motor skills such as grasping a pencil, controlling the pressure applied on the paper, and coordinating the movements required to form letters. Similarly, buttoning a shirt involves manipulating small buttons and aligning them accurately with buttonholes, which is another clear example of fine motor skill use.

In contrast, the other activities mentioned—climbing stairs, catching a ball, and running a race—primarily focus on gross motor skills, which involve larger muscle groups and general coordination. These activities require balance, strength, and larger movements, rather than the fine-tuned control required for tasks like writing and buttoning. Therefore, the choice involving writing or buttoning shirts is the most closely related to fine motor development.
