Dear teachers and students,
I find this article, written by one of my colleagues at
MME/NIE (Maths & Maths Education at National Institute of
Singapore), helpful to us in our teaching and learning of
maths:

Personally, I have applied the five components in my
classroom teaching, except that I did not unify them into a
systematic framework as described by Dr Lee.
Enjoy!
Cheers,
Wen Shih
