Overview Download Transcript (PDF)
David Foster, mathematics education leader and mentor, describes the outcomes of the re-engagement part of the lesson.

David cautions the educators to be precise in their own thinking, especially in labeling their instructional materials—for example, not using the term acute, but acute triangle.
