    As a former 7th grade math teacher, I would select the Circumference vs. Height task primarily because of what I know now vs. what I knew then. Because of the cognitive psychologists’ learning strategies, specifically interleaving, which suggests that we learn best when concepts are revisited in different contexts, the Circumference vs. Height task interleaves multiplication, multiplicative comparison, measurement, spatial reasoning, geometry and the meaning of pi as the relationship between circumference and diameter. Rich task, requiring perseverance, inquiry, cognitive dissonance.
