But neither should compasses anr ruler constructions be taugth at that
age, and for the same reasons.

We are talking about 5-yr olds here, not "citizens". They can meet
the concept later on with a more mature mind [piaget again] and handle
it a lot more readily ...if they are prepared otherwise. What is
lacking in the philosophy that anything can be taught at any time if
it is made simple enough is that the time spent on the "elements" of
many topics could be better spent on the time to learn variations of,
and then at least some mastery of fewer topics of more general
application. All we are seeing is a new name for what was once called
"The spiral approach to learning." which simply failed, as students
did *not* retain what they had learned in order to continue from the
point left, and which then reuired much, and continuous review ...and
still does. It's like reading a large book by taking a few words form
each chapter, and then he next day a few more. Surely it is better
from beginning to end without interrrupion.
