I remember throughout school very little reminders about the logic behind things, which for someone who doesn't grasp it easily, is absolutely crucial. To list the distributive property might be part and parcel, even if secondary, to explaining that the 2 is actually a 20, instead of just saying: " we add a zero ," or even "we do so because it's in the tens place." I believe maths teaching goes too much in stages, myopically, whereas things like this would have helped me to conceptualize!
