One key insight from this resource is that engaging students in exploratory and analytical talk, beyond simple question-and-answer exchanges, helps develop their reasoning and critical thinking skills.

In the context of teaching and learning mathematics in senior high schools, this concept can be applied by structuring lessons to encourage students to verbalize their mathematical reasoning. For instance, when solving a word problem, I could prompt students with open-ended questions such as "What strategy could we use here?" or "Why do you think that’s the best approach?" These types of discussions will help students not only articulate their thought processes but also challenge each other's reasoning, reinforcing their understanding of mathematical concepts.

This method could be implemented in various classroom settings, such as group work, discussions, or through 'think-pair-share' activities, where students first reflect on a problem individually, then collaborate in pairs to share their ideas before a larger class discussion. By planning for these moments of dialogue, I can help students deepen their mathematical understanding through active engagement with peers.
