no l must say he is at the best school.maybe a teacher working hard then asked (told)to run the mathlets and they train for it a few times a week

if l may ,,it all started when l did my anything l should know with the kids this mornings (as they know l will tickle to get the information )find out the boy 11yo is in the mathematical olympiads so there a bit fuss made blu blu .This is a big contest schools put in teams and they are tring to get a good score ,its like a footy team thing ,kid want to make the team and our shows that don"t give up on the public system our school ranks up there with the bigger schools

debate starts now
question 1-D
A rectangle has a perimeter of 90cm .the length of the rectangle is 25 cm
more than the width

find the of sq cm in the area of the rectangle

you have 6 Minutes

2L + 2W = 90 and L = 25
2W = 90 - 50
W = 20

Area = L X W = 500cm2

now wisdom thats what we need at our schools work hard climb up off that bench and get of the field and be a player

[silentC]

L (are you listening?) doesn't (have you got this?) equal (ready?) 25cm

L is 25cm more than W. Therefore L > 25cm.

No wonder the country is going down the gurgler

I bet they put that line break in there to sort out the ones who can read more than one line at a time from the ones who can't.

[SPIRIT]

now l must know how long did it take to work out the first question

[SPIRIT]

now you must say this a better debate than clean your room rebate for the morning

Ability to read and understand the question is just as important as getting the answer.
If you can show that you understand the question, show the calculation steps clearly but get the wrong answer you should still get some marks in an exam, at least that was the way I was taught 50 odd years ago.
If each person is allowed to put their own slant on a question the system fails.
Imagine the final result if engineers each interpreted calculations for a bridge in their own way.
There has to be a standard.

[silentC]

I still want to know how they read newspapers if they mentally insert a comma at every line break!

Thats why we try to keep everything we do looking the same as everything else we've done. We try to
make our plans clear and easily readable.
However I am often faulted for only reading the first paragraph of a standard and applyi
ng it; only to have
it come back from

review with 'But this only applies to rural roads' or something.

And newspapers justify all their text to fit the line, they dont leave three quarters of the line empty before continuing the sentence on the next line.

Do you know how often they find mistakes in high school exams and uni exams? It is not uncommon. Student always end up getting full mark for the question.

Have I ever proven my 4 unit maths teacher wrong? Yes, a number of times. Have I ever been wrong? Yes, many many times. So it is all about if you have the conviction to stand up and question it.

If the argument here is about the interpretation of the question then this simple maths question has become a “trick question”. And we all know that trick questions are not for smart people. They are for smartarses.

And newspapers justify all their text to fit the line, they dont leave three quarters of the line empty before continuing the sentence on the next line.

We don't have the original exam paper in front of us to be able to say whether they did that or not. The point is, it is ludicrous to suggest that a carriage return implies a comma in the absence of a full stop. And you know it.

OK someone please tell me. What the hell is "more than the width" for then?

And how come there is a space between 90cm and . but none before the t

How come it is "the length" not "The length"

[silentC]

According to these knuckleheads, it means that the length of the rectangle is 25cm, which is more than the width.

[Burnsy]

now l must know how long did it take to work out the first question

Less than a minute but longer than it should have

Take your answer of 350 to the teacher and see what she says. A good teacher is quite happy to admit they are wrong to their students, it shows that everyone is human and makes mistakes, teaches kids more than being right all the time. My students expect me to make mistakes, especially in spelling and they are happy with it that way.

Maths is next period, I will write it up on the board exactly as it is here with the line break and see how long to get the correct (350) answer. Also will see how many come up with the wrong interpretation.
