Have I mentioned that each school corrects its own students' tests?

I mean....the whole section on selection without replacement...doesn't that get us into Combination territory?

Now I'm starting to wonder.....maybe the book did cover combinations.

"It's a combination."

"It's a combination. I know it's a combination. I got it right."

"It's a combination."

"Christopher! That's what I just said! It's a combination. Your answer is a permutation, not a combination."

"It's a combination." [note: not an accidental repeat]

"It's a combination. I know it's a combination. I got it right."

"It's a combination."

"Your answer is a permutation, not a combination."

"It's a combination."

"Your answer is a permutation, not a combination."

"It's a combination. I know it's a combination. I got it right."

"It's a combination. I know it's a combination. I got it right."

"It's a combination. I know it's a combination. I got it right."

"Your answer is a permutation, not a combination."

Are you dizzy yet?

The bad news is that apparently I can't understand what the he** he's talking about any more than I can understand what Ms. K is talking about half the time.

"Christopher, you got that answer wrong." [re: the answer Ms. K has in fact marked wrong]

He learned how to do combinations in class.

That's the good news.

I have good news and bad news.

He learned how to do combinations in class.

5. Christopher wrote the Permutation answer in the blank. 1320.

3. Christopher then decided that item number 17 was not a Combination, but a Permutation.

"It's a combination."

"It's a combination."

I wish I had a digital recording of the numerous permutation-combination exchanges Christopher and I have had today.

"No, I didn't."

Did Ms. K tell the kids she has to take points off for crossed-out work because you aren't allowed to cross out work on the state tests?

And....here's the biggie.

And....here's the biggie.

Does the school need to dig out all the state tests Ms. K scored and check to see how many points the kids lost for crossing out incorrect work?

Ms. K covered combinations in class, but Christopher forgot to tell me, and of course there was no review sheet, because why would there be a review sheet when you've covered 18 or 19 or 20 brand-new topics in probability, some of which aren't in the book, in 2 weeks' time and now you're going to give a test?

So he missed the combination problems.....

In the middle of chewing that one over (POINTS OFF! FOR FAILING TO OBSERVE MANDATORY STATE TEST STYLE AND USAGE REQUIREMENTS! I'M PRETTY SURE I'M AGAINST IT!) I was seized by an impulse to check.

....also, there seems to be a new mystery concerning POINTS OFF for crossing out incorrect work on your test paper.

Christopher is under the impression that Ms. K. has told them she has to take POINTS OFF for any crossed-out incorrect work, because the state tests don't allow you to cross out incorrect work. So: POINTS OFF.

So anyway, I had no idea combinations were going to be on the test, so I didn't teach myself combinations and thus couldn't reteach combinations to Christopher & assign practice problems, etc., etc.

What are our mandatory state test syle and usage requirements, anyway?

I mention combinations, because combinations aren't in Christopher's textbook.

Is this a combination or a permutation?
