Deborah Loewenberg Ball, the full quote, so solid, knocking me back into line a bit:
It’s interesting because these problems – speaking of context – aren’t really contextualized. We’re not making them into fake cakes or breads or anything. They really are just shaded rectangles. And the kids are finding them very challenging and interesting. So I do think, on the question of context, it’s worth remembering that mathematics itself is a context and that puzzle-like problems are often both very engaging for kids and good equalizers because kids looking at those diagrams aren’t shaped by some of those same inequities about kids’ experiences. There are certainly differences in their experiences but they’re not the same as problems about how cakes get shared or other kinds of real-world things.
