Worthwhile Mathematical Tasks

> Challenge:

Transcript:
"The importance of selecting "worthwhile" mathematical tasks is addressed in the Teaching Principle of the NCTM's Standards 2000 (pp. 18-19). For this challenge, you are to analyze this aspect of the geometry lesson, paying attention to both the nature of the tasks posed and to how they were sequenced in the lessons.

To help you get started, focus on this task that the teacher introduced near the end of the first day's lesson."
