If you're here about Maths Primary School, I talk about that at the end of this page. But, if you missed Question 10a of the aMAZEing Math Maze - well, I'll talk about that first.
You were supposed to look at this line of best fit and match it to the proper formula from the following choices -
a) y = -x + 6
b) y = x + 6
c) y = -x + 3
d) y = x + 3
a) y=-x + 6 ... If the coefficient of x is positive, the line goes up. If it is negative, the line goes down. In this case the coefficient of x is a negative 1, so the line should go down. Choices a) and c) both have the lone going down with a negative coefficient of x. So we can eliminate choices a) and c).
b) y = x + 6 ... This looks like a good choice. What happens when x = 0? Do you see that when x = 0 then y = 6? Does the point (0,6) lie on our line in the chart? It looks much closer to a 3 than a 6 doesn't it?
c) y = -x + 3 ... We already talked about this when we rejected answer a). This line is going up.
d) y = x + 3 .... Yup, that's the correct answer.
Once again, I am slightly puzzled. People are evidently doing searches for this. What does the word Maths mean? Math is short for mathematics. But why is there an s on the abbreviation? Ah well, I digress.
In Missouri we call it Elementary School, but - as I understand it, we are meaning the same thing. I'm going to recommend a site that I have recommended on other pages - ABC Mouse for children ages 2-7. If you have any thoughts concerning their services I would love to hear them. As I have said - I don't receive a kick-back or anything, they just looked like a good site. They give you a free month and then start charging $7.95 a month (or it least that was the price as of this writing. They've won several awards and - perhaps best of all - they don't compete with me. If you have some recommendations - of any kind - I would love to hear from you.
I've been thinking about starting a forum of some kind.
