Looking for something else, I stumbled on this ... took a few questions and realized ... I'd never get into high school.

And if this is any reflection ... how'd I get there in the first place ?


enjoy, all you fathers that got this far and have no idea how we did it.

Happy Father's Day

You don't go into eighth grade knowing this stuff, it's what you learn once you get there.

Yeah ... and I realize it looks like I’ll STAY there for a while ... THAT was my point.

I was already taking beginning algebra, which is what a lot of the stuff mentioned is, in the seventh grade!

Aw, man! That's sad. Sucks to be you.
I take it that you use no math skills at work to keep your skills honed.
Most trade skills require math skills.

Wow. I think the organizers have to go back to school.

For the heck of it, I took the first test, got 20/20 and received a grade of 92!!!

Skill practiced Number theory: Factors
Time spent 2 min 31 sec
SmartScore 92
Problems correct 20/20

It’s all in your head still....All you’d have to do is brush up a bit for a few hrs and you’d pass 8th grade. : ~ )

btw - I think about 40% of the 8th graders would fail.

A lot of the beginning math in that group are things we introduce to our kids in fourth grade. They've been working on some of these concepts for several years by eighth grade.

That makes it easier to get through the new stuff ffurther on down that list.

They organize math differently now.. they “section” it so in each grade they learn a tiny bit of algebra and geometry .. but the time they hit 8th grade they are ready to put it all together ..

I'm 63 and I guess if I DID spend some time "brushing up", I'd probably pass, but it was that first glance/attempt that showed me new words and phrases.

I learned LCD, Least Common Denominator not ... whatever it is now.


Actually, I just retired as a truck driver and my job was to make a lot of money and get no sleep, have no life, don't kill you and don't get killed.

The hardest and most demanding part of my job was staying awake and maintaining health.

“An envelope measures 12 centimeters by 9 centimeters. A pencil is placed in the envelope at a diagonal. What is the maximum possible length of the pencil?”

Your Answer: _________ centimeters

Then you must be well skilled at time/speed/distance problems.
You've got the skills, you just don't realize it.
And now you get to concentrate on the other things you missed out on while driving.

Hint: a squared + b squared = c squared

a = 12, b = 9, c = ?

THAT one I remember from my roofing days ... Pythagorean Theory;

I think it is ...

The hypoteneuse of a right angle is equal to the square root of the sum of the squares of both sides

Probably worded wrong, but I can finger it out

Your answer ... 15 (I hope/I think)

Correct! That was the first (and only) question I checked. One thing for sure, math and science tests have been severely dumbed down over the past decades. All in the name of “social justice”, you know. /s

And this was AFTER he got his ‘brainiac award’ from the so-called Wizard! It should of course have been a right triangle.

Just yesterday evening my neighbor was standing there watching me beat a battery cable connector onto my car battery with a pair of vise grips. He says "you want a hammer?" I said "I already have one..."

And what percentage of eighth graders actually achieve all those math goals each year? From news story after news story, it’s doubtful many in the annual HS graduating classes have achieved them.

Most anyone can put together an impressive list.

“The sum of the square roots of any two sides of an isosceles triangle, is equal to the square root of the remaining side.” - Scarecrow, Wizard of Oz

Also, it isn’t “any” 2 sides, but rather the 2 shorter sides vs the diagonal: (a^2 + b^2 = c^2)

Not only do you save steps, but you avoid the quandary over choosing the right hammer.

The list is purely wishful thinking. The vast majority will barely be able to multiply 3 digit numbers together, much less that other stuff.

Actually, that one didn’t require the application of pythagorian theorem to solve, because it was a 3-4-5 triangle...3x3=9, 4x3=12, so the hypotenuse=5x3=15

If you don’t get the 8th grade material, go back and start at a lower grade and work your way up!

I always preferred to memorize/use the more general formulas rather than the special case short cuts. Less to remember that way.

4 is not a factor of 20? Hmmmm, I picked 5 and 4 a got it wrong, I am still trying to figure that one out.

What diameter is the pencil?

Does it have an eraser?

Is the eraser(if included) count in the length of the pencil?

If it is a mechanical pencil is there funding to get a custom length one made?

While 5 x 4 = 20, you can reduce 4 further to 2 x 2. Therefore, the factors of 20 are 5, 2, and 2. (5 x 2 x 2).

I agree that they were not specific enough on the question. I was suggesting that they were looking for the prime factors of 20. The only prime numbers that are factors of 20 are 5, 2, and 1. They must be playing that fun game in school that I always hated: While your answer is correct, the answer on my test is more correct.

The pencil will not fit if you try to use one that is the square root of (92 + 122) in length ... the volume of the pencil will draw up the surfaces of the envelope, reducing the lengths of the two legs of that right triangle just enough that you will not have the pencil of that length entirely "in" the envelope.

You're assuming it's a traditional envelope. Perhaps it is an expandable packing envelope.

I pulled that question from the posted website at the top. Seems the questions change with a refresh. Anyway, the metric system (fractions of ten) is a much more logical system. Unfortunately, it would be way too much hassle trying to implement it regularly here.
