Mind Trick
and another one
Last week I purchased a burger at Burger King for $1.58. The counter
girl took my $2 while I was digging for my change. I then pulled 8
Cents from my pocket and gave it to her. She stood there, holding the
nickel and 3 pennies, while looking at the screen on her register.
I sensed her discomfort and tried to tell her to just give me two
Quarters, but she hailed the manager for help.
While he tried to explain the transaction to her, she stood there and
cried.
Why do I tell you this?
Please read more about the "history of teaching math":
