When I went to elementary most of the older teachers had not even attended university.  They had completed high-school, went directly to Normal School, and then straight into teaching.  But one thing was for certain:  They all knew how to teach arithmetic until we all knew the basics.

The Ontario government could probably visit some retirement homes and look for elderly teachers for lessons on how to teach mathematics.  It's guaranteed that these old folk could still teach math better than the clowns who have messed up today's system.
