Failing Math Standards

This just in from my newsfeed,

“WASHINGTON (AP) American students have a math problem.

The latest global snapshot of student performance shows declining math scores in the U.S. and stagnant performance in science and reading.

Education Secretary John B. King Jr. says this country is losing ground and he finds that to be a troubling reality when, in today’s economy, ‘the best jobs can go anywhere in the world.'”

anythingelseWell, hello hello, the same news story has come out of Australia and New Zealand recently too. In fact, Math scores are falling in most western nations (see: http://www.nzherald.co.nz/nz/news/article.cfm?c_id=1&objectid=11757118). The politicians are placing the blame at the feet of teachers (see: http://www.nzherald.co.nz/opinion/news/article.cfm?c_id=466&objectid=11759955) and teachers are placing the blame at the feet of math-deficient parents and parents who never could do Math are blaming anyone who will listen. It turns out that Australian 15 year olds are now two years behind their international peers (see: http://www.smh.com.au/national/education/australian-school-students-two-years-behind-worlds-best-performing-systems-20161206-gt4w8p.html); and 15 year old math students in the ACT (Australian Capital Territory) are 18 months behind their overseas peers in Mathematics. So, who is to blame – the media, business, test scores themselves, or perhaps…no, it can’t be…the students themselves??! Oh, this debate will rage as long as Mathematics is being taught or, perhaps, trying to be taught? (Note: students themselves hardly ever get blamed for this decline).

Prize Object Puzzle: If Sue does not know where the prize is in the first question, it can’t be under the square. She must have been told it is under another shape. Apply this same logic to Colin. It is then obvious that the prize cannot be under a yellow object. That helps Sue eliminate her yellow shapes. Got the idea?

Algebra Puzzle: Answer = 1

Number of tabs? According to Lifehacker, the ideal number of tabs you should have open is nine. Yes, a single digit. To some, this is like playing a piano and only using a fraction of the notes!

Worst Graph? Where to start. What a visual mess and even some of the lines merge and are impossible to follow. A graph is a visual display of data, with the goal to identify trends or patterns. This is a spider’s web of information which fails to show a clear pattern at all. Solution? Well, different colors would help, or why not group in two or three graphs where trends are similar?

Homework Puzzle; The total value of the counters is 486, so halve this to get 243. Now, arrange the counters to equal this amount twice.

The graph on the left (Coronavirus) is for a time period of 30 days, while the one on the right (SARS) is for 8 months! Very poor graphical comparison and hardly relevant, unless it is attempting to downplay the seriousness of the coronavirus?

10 x 9 x 8 + (7 + 6) x 5 x 4 x (3 + 2) x 1 = 2020

NCEA Level 2 Algebra Problem. Using the information given, the shaded area = 9, that is:
y(y-8) = 9 –> y.y – 8y – 9 =0
–> (y-9)(y+1) = 0, therefore y = 9 (can’t have a distance of – 1 for the other solution for y)
Using the top and bottom of the rectangle,
x = (y-8)(y+2) = (9-8)(9+2) = 11
but, the left side = (x-4) = 11-4 = 7, but rhs = y+? = 9+?, which is greater than the value of the opp. side??
[I think that the left had side was a mistake and should have read (x+4)?]
