This document discusses strategies for extending conversations with children through expansions. Extending conversations helps children develop language and thinking skills. Teachers can expand on what children say by adding more language, asking questions, and introducing new vocabulary. This scaffolds children's conversations and benefits their learning. Specifically, expanding conversations increases children's vocabulary, models back-and-forth exchanges, and enhances their understanding of new concepts. It also provides teachers insights into children's knowledge and ideas for curriculum planning. The document provides examples of expanding children's words to scaffold both their language and thinking.
