What does a kindergartner reading a story to a doll suggest about their understanding?

When a kindergartner reads a story to a doll, it demonstrates that they understand the concept that written symbols convey meaning. This skill is a foundational aspect of literacy development, indicating that the child recognizes that the text they are reading is not merely a collection of letters but rather represents ideas, stories, and information that can be communicated.

This scenario illustrates the child's ability to associate words with their meanings, which is a crucial step in learning to read and comprehend. Engaging in this type of imaginative play reflects an awareness of the function and purpose of reading. The child is likely mimicking the reading process they have observed in adults or caregivers, showcasing their understanding of how stories are shared through written language.

In contrast to the other choices, while storytelling techniques, fluency, and vocabulary practice are important components of reading development, the primary takeaway from this behavior is the child's recognition of the relationship between written symbols and meaning. Thus, the act of reading to a doll highlights their grasp of this essential literacy concept.
