When my fourth grade teacher was teaching us about time (ie, if the time is
9:00 AM and your train leaves at 1:30 PM, how long do you have to wait?)
Her idea was to find a clock (one with hands, this was before digital clocks)
As you look at the clock count off the hours between 9 and 1 then add the half
hour to get 4 and a half hour wait. I went home and asked my mom about all
this My mom said change any time after noon to 24 hour time. 1:30 PM =
13:30, so 13:30 - 9:00 = 4:30. She then showed me how to subtract 13:30 -
9:45 etc. I went back to school the next day and during math time worked the
problems the way my mom said. The teacher couldn't understand how I figured
the answers so quickly. I explained it to her, but I'm not sure she
understood. I don't remember more than that.
(My mom always helped with my homework and I think that is a good reason I
learned so much. Even when I was in high school algebra, my mom --not
remembering any algebra she had-- would figure the word problems out with
basic math and then I would figure them out algebraicly based on what she did.
But that is another theme)

showing my seat-neighbor how to subtract 5 from 3 and get -2. The teacher,
thinking I was wasting time, ridiculed me by grabbing three pieces of
chalk from the chalk-tray and defying me to subtract 5 pieces and show her
the remaining negative 2 pieces. I was devastated, put my head on my desk
in shame, and didn't participate in arithmetic for a couple of days. >>
