What does Christianity have to do with education in schools? The mere question seems set to trigger a host of entrenched tensions, well-tested arguments and political postures. It risks launching us into one more round of heated debate about religion and society, and might be more likely to achieve heated reaction than thoughtful reflection.
My point here is not to advocate for a blanket approach to mathematics, or even to claim that this is the best mathematics book chapter ever. My aim is simply to ask us to think about how the way we picture the world, our deep-down beliefs about how things work, might influence what happens in classrooms, whether or not religion is getting mentioned.
