Which of the following is a 4-year gross motor milestone?

• A. Skips on 1 foot
• B. Draws a simple cross
• C. Grasps pencil with thumb and fingers
• D. Unbuttons and buttons

Answer: (A)

At around four years old, children demonstrate advanced gross motor skills that show balance and coordinated leg movement. Skipping on one foot embodies this level of gross motor development because it requires balance, leg strength, weight transfer, and smooth, coordinated motion. It’s a hallmark of four-year gross motor milestones.

In contrast, the other tasks are fine motor or self-help skills: drawing a simple cross relies on precise hand movements and drawing control, grasping a pencil with the thumb and fingers reflects refined grip development, and unbuttoning and buttoning are dexterity tasks tied to fine motor and self-care abilities rather than gross locomotion.
