Area, volume and such. I looked at his paper when he was figuring the volume of a cylinder.
he had 2 x 3 x 1
I asked him what the 3 was repersenting. gues what I was suprised to hear. "It was pi" I told him that pi is 3.14. He told me that his teacher had told them to round pi to 3.
BTW my son is in 7th grade.
I called the teacher today to discuss this with her.
Here ware the reasons they round pi to 3
1. Its easier to multiply a 1 digit number rather than a 3 digit number.
2. The TAKS test (I am in TEXAS) is easier to figure the correct answer if you round pi, you don't have to make sure you round correctly your answer during the test.
3. Most of the parents are happier becuase its easier for them to help with homework.
And the #1 reason to round pi is
are you ready
are you sure
are you really sure
well her goes its a freakin duuuzzzzyy
"Well all the calculators have pi on them anyway."
I put this in quotes because that was her exact words
As a high school math teacher, this disgusts me...
PS - sorry for bumping a year old thread, it was linked to on the dark side.
