Interesting post on Aus-DotNet
My kids had a maths sheet sent home for homework (primary grade 3) and one of the questions was: fill in the missing number.
4 / ? = 0
This apparently is a Dept of Education homework sheet.
After approaching the teacher, who believed that the answer was zero, and principal who referred the response that this was totally incorrect to higher powers, this was the response I got:
the answer to your question is as follows:
The children need to know the associative law:
2 x 0 = 0
2 divided by 0 = 0
They need to know the relationship between multiplication and division as we learn our times tables. The aim of this problem is also to understanding how division and multiplication work.
They also need to know that zero is a place holder.
How scary is that?
I would say the majority of parents wouldn't even know that '4 / 0 = 0' is wrong. I am utterly appalled by this.
