Overview

This part begins to articulate the practice of narrating by exploring what is involved in narrating the construction and use of a number line to compare fractions.

Key Points

• When practicing narrating, use the actual language that would be used with students. That is, avoid talking about what “might” be done or “would” be said to students. Instead, talk as if talking to a class.
• Narrate while doing the construction. Do not wait until after the representation is constructed to explain what was done.
