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.

Or the “3, 4, 5” rule:
{{(3)4}+{(3)3}}^2={(3)5}^2
etc.

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)

...beat a battery cable connector onto my car battery with a pair of vise grips.
A perfect example. Why waste all that time and energy going to get a 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.

Ball pein ...without a doubt. If you've got to make the trip then at least get the right tool is my way of thinking.

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

IXL is a terrific site, works as well as tutoring for both my kids
If you don’t get the 8th grade material, go back and start at a lower grade and work your way up!

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?
To: jpsb
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).
