#1 Re: Help Me ! » Functions: names to put "sign" and "up/down" in a scheme? » 2017-05-27 00:12:11

Meanwhile I already found the word sign table.
But how do you call increasing, decreasing... in one word? The ... of a function. In Dutch we call it "verloop", but it's the same like process..., but what's the right mathematical term?

Hi
I'm a Belgian CLIL teacher and I'm teaching CLIL maths since September.
Next week I want to start with functions, but I have the problem I can't translate some things.
Can someone please help me what the name is in English?

1) First one is a kind of scheme/table where you can say if a function goes up or down.
It looks like this for a linear function (the arrow goes to the right and up if the function/line goes up and the arrow goes to the right and down if the function/line goes down):
   x |       
--------------------
f(x) |     -->

2) The second one is a kind of scheme/table where you can say if a function is positive or negative.
This example is when the zero of the function is (5,0) and the straight line goes up.

   x |       5
--------------------
f(x) |   -  0   +

Hi
I have another questions about special binomial products.
The first one is (a+b)²=a²+2ab+b² as we all know, we call it the square of a binomial, right?
The second one is (a+b)(a-b) = a²-b², how do you call this one? The only thing I found was add times subtract, but it sounds too easy compared to our name for it. wink

Hi both
I'm very happy I found a solution for my questions. The internet is full of things, but sometimes you might not find that one specific thing. Thanks to you I know it now. wink
And about the CHECK: yes, in Dutch as well it's a big problem. So it's not only a British problem. We face the same problems, whether there's a BREXIT or not. wink
We already had exchanges with 2 British schools in the past. One in Bernard Castle (near Durham) and now one in Reepham (near Norwich). We hope we can keep exchanging with the school in Reepham.
Thx a lot!

Hello all
I'm a maths teacher in Belgium. Uptill last year I was teaching maths in my mother tongue (Dutch), but since the 1st of September I'm doing CLIL and I'm teaching maths in English next to Dutch.
Most of the vocabulary can be found on the wonderful website "mathisfun.com", but some of the things we use I cannot really find. I hope you can help me.

1. In our school books we use several steps to solve a problem: GIVEN - ASKED - SOLUTION - ANSWER - CHECK. Are these correct or do you call it different in English? In our school English teachers put the focus on British English, so I prefer B.E., but A.E. or any other is better than nothing.

2. At the end of an equation, we write "Oplv.V.=" which means Solution Set of an Equation. Do you also shorten it? If so, how?

3. I guess you call "1/3" a third and "2/3" two thirds. One of the students of our school (who is American) told me. Do you call "1/4" a quarter or a fourth, or do you use both names or s.th. else?

That's all for now.
Thanks
Bart
