If you teach maths in a JIT fashion, when do you learn "basic facts" like 3+4=7?
If you don't teach that stuff systematically, how do students get to the point where they feel they can apply maths reliably - e.g. adding prices together in their head?
So you need both - a solid foundation, plus applications using that foundation plus a bit more.
Absolutely you need both. We agree there. And any reasonable curriculum - in practice - will be a combination. But the curriculum will still be organized in some fashion, it's a very high-level document after all. And that's where one or the other flavor will come through.
