ATOT, are you smarter than my 3rd grader?

Teacher is wrong.

My work as I went along:

Code: 
o p
o p o p
o p p
o p p o p p
o p p p
o p p p o p p p

Her pattern would be:

Code: 
o p
o p 
o p p
o p p o p p
o p p p
o p p p o p p p o p p
 
That's a pretty complex question for a third grader IMO. My 3rd grader is pretty smart, I'll give him this question tonight and see how he does 🙂

In any event, teachers make mistakes too - don't sweat it. My eldest son got some homework in 1st or 2nd grade that frankly didn't make any sense. We helped him do the best he could on it. The sad thing is that the next day was a school open house and another parent came in with the homework assignment and started screaming at the teacher about how ridiculous it was, before crumpling it up and storming out of the classroom.

either answer (2 owners w/ 3 pets each or 3 owners w/ 3 pets each) would fit in the (barely) established pattern.

Sounds like most of the class will probably get the wrong answer. If the teacher is worth their salt, they'll probably discuss the question in class for a minute and give credit for the "wrong" answer.

Yeah. After reading your post I can see where there really isn't enough information to establish a definite answer.

I always did good in math except for getting points taken off for not showing work or working the problem in a way that was different from how the teacher showed.

I'm docking points right now for agreeing with 3 owners, 3 pets each and not explaining your reasoning.
 
Just get her to explain the pattern to the teacher and have them fix the mark.

I had a college professor get a sign wrong on a formula and followed it through making everything else wrong. The best part was pointing it out, him disagreeing and continuing. After the lecture I showed him why it was wrong, and by the time I got home the class had an email from him saying that he was re-doing the lecture next class 🙂

People are human.
 
It's kind of an ambiguous question. They should be more clear what the pattern actually is. Anyway, I don't see how you could get 3 owners, 3 pets as a continuation.

Total Owners:Total Pets
1:1
2:1
1:2
2:2
1:3

2:3

----------
O - Owners, P-Pets

O-P
O-P O-P
O-P-P
O-P-P O-P-P
O-P-P-P

O-P-P-P O-P-P-P

second row, each owner has 1 pet
fourth row, each owner has 2 pets
sixth row, each owner has 3 pets

sets of pets are increasing by one, so the sixth row has 3 sets of 3 pets. 3 owners with EACH one having 3 pets.
 
I got 3 owners with 3 pets each = 9pets.. im dumb i guess

Going over it again im not sure why I saw a pattern for 3 owners when there isn't one. Should be 2 owners each having 3 pets

Fail.
 
I get 2 owners 6 pets

I wrote it down like this. O is own, P is pet
1) O P
2) OO PP
3) O PP
4) OO PPPP
5) O PPP

O alternates between O and OO, so row 6 will be OO. P is relative to O. First you get 1 P for each O, so it goes OP then OOPP. Then it has 2 for each O, so it goes OPP, OOPPPP. Then it goes up to 3 P for each O and the fifth line is O PPP. Next would be (OPPP)*2 = OOPPPPPP
 
Now I'm going nuts trying to figure how 3 could possibly be a right answer. There probably is some series pattern under which O3, P3 is the correct 6th row.
 
I have no idea how any of you morons are getting 3 owners with this very simple pattern

OP|OPOP|OPP|OPPOPP|OPPP|OPPPOPPP

Lol overreaction much? Happens in college too. In my last calculus class everyone was stumped by one problem and no one knew how to solve it. Many of us had spent hours trying. Guess what? That integral table in the back of the book that we'd never been allowed to use? For that problem we were apparently supposed to use it. The outrage in the class when the prof told us was pretty hilarious.

Possibly by division...

row 2 is 2 pets and 2 owners...2/2=1
row 4 is 4 pets and 2 owners...4/2=2
row 6 is 9 pets and 3 owners...9/3=3

If that's it this should not be presented in the third grade

Nice way of expressing it. Makes it easier to see the pattern.

Most stimulus I've gotten all week is from a 3rd grader's homework. Either I need a new job or I need to start having kids.
 
1. A B
2. AA BB
3. A BB
4. AA BBBB
5. A BBB
6. AA BBBBBB

The part of 2 owners with "1-3 pets each" is necessary to prevent answer on Row 6 from having either 6 or 8 as an answer. But there is no precedence in the limited pattern to show that there would be 3 owners.
