A pediatric clinic is reviewing developmental milestones for medical students. Match each clinical presentation of a child's highest level of developmental achievements across four domains (gross motor, fine motor, language, and social) with the corresponding typical chronological age.
- Can run, build a tower of 6 cubes, use two-word phrases, and engage in parallel play.24 months (2 years)
- Can ride a tricycle, copy a circle, use three-word sentences, and state their age.36 months (3 years)
- Can hop on one foot, copy a cross, draw a person with 3 body parts, and engage in cooperative play.48 months (4 years)
- Can skip, copy a triangle, tie shoelaces, and independently dress themselves.60 months (5 years)
Answer
The milestones should be matched as follows: the running/2-word phrase child is 24 months, the tricycle/circle child is 36 months, the hopping/cross child is 48 months, and the skipping/triangle child is 60 months.
Each clinical presentation is carefully grouped to represent the hallmark developmental milestones of a specific age across all four domains. 24-month-old children combine two words and use parallel play; 36-month-old children ride a tricycle and copy a circle; 48-month-old children hop on one foot and copy a cross; and 60-month-old children skip and copy a triangle.
