KQs: What knowledge is worth knowing? What makes knowledge valuable?
I have four teenagers. I’ve spent a lot of time working with them on their math homework. More often than not, after helping them answer whatever questions are assigned that day, I’m left with questions of my own — questions that I can’t find good answers to. Why are we teaching kids these things? Does anyone actually use the math we are teaching in their daily life? Is there any benefit at all to learning this stuff? And are there not more interesting and useful things we could be teaching them? Don’t get me wrong. I’m not anti-math. I use mathematical thinking, statistics, and data analysis constantly, whether I’m writing economics papers, trying to get better at golf, or hoping to pick winners at the race track. But here is the thing: the math tools I actually use, and the math tools I see people around me actually using, seem to have nothing to do with what my kids are learning in school. Which makes me think that we must be able to better for our children when it comes to teaching them math.
