A new Teacher Rainbow walked into a class
one morning and after greeting the
students, he asked, “Do you know what we
are going to be teaching today?”
The students all chorused, “No Sir!”
Then he said, “Then there’s no point
teaching you what you don’t know.” and he
left.
The next day, he came in and asked, “Do you
know what we are going to be teaching
today?”
They all answered, “Yes Sir!”
Then he said, “Then there’s no point
teaching you what you already know.” and
he left again.
The third day, he came in and asked again,
“Do you know what we are teaching today?”
Then the students answered randomly,
some saying yes and some saying no, then
Rainbow said, “Those that know should
teach those that don’t know”, and he left.
