I think the point on how mathematics is incrementally built is the main take away.

My issue with many of the maths courses especially in early primary classes is that they lack rigour. It seems to be about solving practical problems (calculating grocery lists totals etc.) rather than really understanding what happens when you do arithmetic. There are some things that genuinely help when memorised (e.g. the times tables) when you're doing arithmetic but that's looked down upon.

I'm trying to remedy this with my own children but it's a bit of an uphill battle. This article is definitely something I can use in my attempts.
