This document provides information about strategies for engaging children in substantive conversation. It discusses three conversation strategies: clarify/extend, question/tell, and think-aloud. The clarify/extend strategy involves listening to what a child says, picking up an idea from their talk, and adding to or clarifying it. The question/tell strategy involves joining a child in an activity, drawing attention to details, maintaining interest based on their efforts, and offering praise. The think-aloud strategy involves verbalizing thoughts and modeling how to think through a task or problem to a conclusion. The document emphasizes that these strategies can help teachers build students' oral language and knowledge through everyday conversations.
