I actually remember when the metric system was introduced in elementary schools. Looking back, there was far too much emphasis on getting all prefixes and their relationships memorized: micro, milli, centi, deci, hecto, kilo, mega. And virtually no emphasis on developing an intuitive "metric" feel for the common quantities in everyday life.
