Which of the following developmental milestones typically occurs at age 3?

At age 3, children typically begin to identify and name colors, which is a significant cognitive developmental milestone. This capability reflects their increasing cognitive abilities and understanding of the world around them. By this age, many children can distinguish and recognize various colors, often naming them when asked. This skill indicates advancements in their language development as well; as they learn to express observations about their environment.

The other options, while relevant in the context of child development, typically occur either earlier or later than age 3. For instance, kicking a ball forward is generally achieved around the age of 2 to 3. Using scissors with control, which requires finer motor skills, typically develops later, often around age 4 to 5. Writing their name represents a more advanced skill that usually emerges around age 4 to 5 as well, as children develop greater fine motor control and literacy skills.
