I realize how it reads but I'm going to go completely left field with this one and ask are you sure it's not a case of bad wording? For instance 22 divided in half equals 11? In which case that makes it true. Because when I first looked at it, that's h how I read it and it took me a minute to figure out exactly what was wrong about it.

Okay nevermind I see where you explained it further. I'd just pull her off to the side discretely.

If she's grading the test with a misconception, she may mark correct answers wrong.....and then a parent will see....and go after her job!!!!!!! Won't you feel bad for not speaking up? [Of course I'm being hyperbolic just for the sake of being a jerk....]

I thought the same thing as Aces but with the full explanation of what is on the Board unless the teacher was showing a misconception on purpose it looks like an error. I would just say, hey, I noticed this on your board, can you share with me how you used this in your class because I'm curious what strategy you were using? Then if the teacher was indeed explaining it the way it looked I'd point that out.

Exactly I saw it as 22 divided by half or in half, not 22/(1/2). Which is a good lesson as well to be particular about how things are worded. And at the same time, if it was in fact 22/.5=11, it could have been something like "Can anyone tell me what's wrong with this equation?" Because I've been known to do that as well, put up an equation on the board and ask what's wrong with it.

Exactly! I think we ALL do stuff like that: model what is correct and what's not and talk about why usually thinking aloud what errors students tend to make. "So I notice students tend to want to... but that's not correct because...'' I usually end up putting an X through the work after we've had a conversation. The best conversations come from talking about errors or mistakes students make or having them tell you why an answer and the work is wrong.

UPDATE: I went into the teacher's classroom yesterday and the exact same problem was on the board. Never erased! And her class is self-contained so the kids have been staring at that problem for who knows how long!!!

Huh. Maybe at that point I'd delicately bring it up.

Looks like it times to hire a new custodian!

Our custodian is responsible for hallways and outside. Teachers clean, sweep, and mop our classrooms.

Our custodians would never presume to erase anything from the board (just as teachers or admin wouldn't).

Ours wipe down our boards every night. If there's something we don't want erase, we write DO NOT ERASE by it. Nice walking into a clean board each morning.I assumed that was a standard janitoriall thing like taking out the classroom trash and sweeping the floors, but I guess it varies more than I thought.

Our janitors clean the bathrooms, hallways, and maintain the school grounds outside, but they only ever shampoo the carpets and mop the floors in the classrooms. Otherwise, the teachers are responsible for their own rooms.

Same. If we don't clean our boards they don't get cleaned. Which is perfect for me because I leave stuff up there all week.

Oh thank God for our strong union! I'm with otter. I'm there to teach, not to be a maid.

Agreed! I also have the kids wipe down desks and clean the whiteboard. They all want to do it! The janitors sweep our floors every night.

I leave my classroom very tidy, but we have janitors that mop and vacuum. That does not fall under my job description.

If I remember correctly, don’t you have a very small classroom and a single whiteboard? It would probably take you all of 5 minutes to clean your classroom.

I don’t think that you need a strong union to prop up a shack.

So if you taught science, for example, and some glassware fell off a counter and smashed on the floor, you would just leave it until the janitors came along?
