Which skill is expected to be demonstrated by a 3-year-old child?

A 3-year-old child is typically expected to demonstrate the ability to hop on one foot, as this skill reflects the gross motor development that occurs at this age. At around three years, children are developing better balance, coordination, and strength, which allows them to perform activities that involve hopping. This type of movement not only showcases their increasing physical abilities but also their capacity to engage in playful activities that enhance motor skills.

On the other hand, riding a bicycle generally requires more advanced coordination and balance, skills that are not typically mastered until around ages 4 to 6. Skipping involves a rhythmic movement that develops later, usually closer to age 5 or 6, as it requires the ability to alternate feet in a coordinated manner. Throwing a ball overhead is a skill that also develops with age, and while some 3-year-olds may be able to throw a ball, it may not be with overhead motion or with significant accuracy or force. Thus, hopping on one foot is the most developmentally appropriate skill for a child of this age.
