In what ways do children's gross and fine motor skills develop during the preschool years?

What will be an ideal response?

A good answer would include the following key points:
• Activity Level
• The activity level is higher at age 3 than at any other time
• Activity (practice) and brain development (neural connections and myelination) are closely linked
• Genetic and environmental factors may encourage or discourage activity levels
• Gender Differences
• Boys have greater muscle strength
• Boys generally have greater activity level than girls
• Girls surpass boys in coordination of their arms and legs
• Other differences in motor skills
• Social factors, including gender appropriate activities
• Practice of motor skills
