What is the difference between gross motor and fine motor skills? Provide examples of each at two age ranges.

• A. Gross motor uses large muscles (crawling, walking); Fine motor uses small muscles (pincer grasp, writing). Examples: 6-12 months: gross (sitting, crawling); 2-3 years: fine (scribbling); 5-6 years: gross (skipping) and fine (printing letters).
• B. Gross motor uses fine muscles; Fine motor uses large muscles.
• C. Gross motor skills include writing and drawing; Fine motor skills include running and jumping.
• D. Gross motor skills involve eye-hand coordination only; Fine motor involve gross actions.

Answer: (A)

Gross motor skills involve large muscle groups and big, whole-body movements, like crawling, sitting up, and walking. Fine motor skills involve small muscles and precise control, such as the pincer grasp and writing. The example set mirrors this distinction and places skills at developmentally appropriate ages: around 6–12 months, gross skills like sitting up and crawling are dominant as the body learns to control big movements; around 2–3 years, children increasingly show fine motor control with tasks like scribbling; by 5–6 years, many kids demonstrate both—gross skills such as skipping and fine skills like printing letters—showing that both domains develop together but at different paces. This alignment of muscle group involvement with age-appropriate tasks makes it the best fit. The other options mix up which muscles are used or which activities belong to gross versus fine motor skills, or reduce gross motor to eye–hand coordination only, which doesn’t capture the full range of large-movement abilities.
