I am a retired old-timer teaching remedial math. I am subject to being old-fashioned.
What are your thoughts on this.
I am insisting that my student learn the US customary systems of unit my memory, no notes. (I allow conversion tables and notes on metric prefixes, etc.)
They think it is unnecessary.
I just do not see that a person has a technical education without knowing how many inches are in a foot, feet in a yard, yards in a mile, quarts in a gallon, etc.
I just gave a test that asked how many inches are in a mile. One of the students said how did I expect him to know this. I do not expect them to know it. I expect them to know how many inches are in a foot, and how many feet are in a mile, and know how to put these facts together with a calculator and get a result.
