ASSESSMENT: (formative and summative): The assessment of the
lesson is two-fold. The first (informal) comes from the observation
of the interaction of the students as they discuss their approaches
to solving the problems. The second (formal) comes from the actual
problems that they create, and their solution of those problems.
