Teaching Math in America

You purchase a burger at Burger King for $1.58. The counter girl takes your $2 and then you hand her 8 cents from your pocket. She stands there, holding the nickel and 3 pennies, looking confused and staring at the screen on the register.

You sense her discomfort and tried to tell her she should just give you two quarters in change, but she calls the manager for help. When you try to explain the transaction to her, she just looks at you and cries..

Why do I tell you this?.

Because it demonstrates the evolution in teaching math since the 1950s:
