My daughter is in the 5th grade in California. Her school uses the state mandated math book and work book. I've been concerned about the teaching techniques up to this point.
Tonight my daughter was showing me a number line technique for determining if fractions are equal, or if one is greater than the other.
As far as I'm concerned the technique is faulty for several reasons. I'll post those after a few Freepers comment.

Why are meters different for boys and girls?

I’m just confused as to which length is a meter. I don’t know that it matters, but the different lengths might confuse a fifth grader.

White men can’t jump [as far as white girls].

The differing scales are misleading. Certainly 4/6 > 5/8.

Well, you don’t need more than 4th grade math in CA, anyway.

4/6 should be farther, but it looks like if you mark it the way they want you to, you’ll think 5/8 is farther.

It doesn’t require them to actually DO math.
Only to know how to count (and read).

Wow. Yank your kid out of public school.
And I support public schools - but my 4th grade daughter would laugh at this problem, as idiotic.

That may be the point. After counting the marks a student may say that 5/8 > 4/6. Perhaps the lesson is also to teach equivalence.

Well. There’s your regular meters and your Title IX meters.

Both lines would have to be the same length before meaningful comparisons could be made between the eights and sixths - this looks like some sort of bizarre semi-psychotic PC scam to show that boys and girls both can jump the same distance even though the numbers seem to show they can’t.....
To: Fundamentally Fair
Just wait 'til they teach her geometry.
To: Fundamentally Fair
The lengths of those jumps should have been made in decimeters, centimeters or decimal fractions of a meter. The point of the metric system is to avoid those “messy” 3rds, 6ths, 8ths, etc!
To: Fundamentally Fair
Are they following this with lessons in fraction conversion with common denominators, etc?
To: Fundamentally Fair
Eagerly await your reasons for the faulty technique.

What books are they using? If they are using Turk or Everyday Mathematics be warned. They use these up here in many of the Washington schools. We had a hard time helping my son with his 2nd grade homework, us not understanding the algoryhtms.
We raised such a fuss about it they finally dropped them for this year.
