Which of the following fine motor skills is expected at 3 years of age?

At 3 years of age, children typically start to demonstrate more advanced fine motor skills that reflect their growing dexterity and control. Copying a circle is a developmentally appropriate milestone for this age group. This skill involves the coordination of hand and finger movements, as well as visual-motor integration. By this age, children are beginning to refine their abilities to manipulate objects and use writing tools, which makes drawing simple shapes like circles a common achievement.

Turning pages in a book can occur around this age, but the ability to do so may vary among children. It is more of a skill that emerges slightly earlier or later than 3 years old, usually between 2 and 3 years. Fisting refers to a grasp present in much younger infants, and tying shoelaces is a complex motor skill that typically develops at a later age, often around 5 to 6 years, when children have better finger dexterity and understanding of manipulative tasks. Thus, copying a circle stands out as the most appropriate answer for the fine motor skills expected at 3 years of age.
