Emily, are you still around? I have a teaching math question for you.
Look, you got a little stabbed the other day. That's bound to make anyone a mite ornery.

Actually, Fay or Hil or one of our parents may be able to answer this question, so I'll just go ahead and ask it.
When do kids learn (or have an understanding of) negative numbers?

I think it was third or fourth grade for me. For a while I was adamant that negative numbers didn't exist.

That's about what I figured.
Last night in after care, my very precocious first-grader was switching all of her homework problems so the answers could be in negative numbers, and I thought that was really pretty advanced for her.
I let her do it, because I figured it would make her teacher laugh.

Happy Birthday, PixKristin and MFNLAW!
I came in to find the subcontractors had removed all my edits and text changes from the new webpages--the ones that took pretty much all day yesterday to make. To fix the CSS problems. The CSS is in a separate file and the html file doesn't need to change to make it apply (or it shouldn't, if you do it right).
I can beat them with pointy sticks for this, right?

That sounds about right. I should remember when CJ was studying negatives, but I'm a-blank.
He does test this weekend to see if he can take Algebra next year. Seventh grade. For Algebra. I'm still agog.

"In the equation E = mc⬧, c⬧ is a pretty big honking number." - Scola
Very advanced. In fact, one of the things I think we railed against in a previous discussion was the tendency of teachers up until second or third grade to say that you can't subtract a larger number from a smaller one!

There was actually a bit of a disconnect for me with it. She writes at least 1/3 of her numbers backwards, but she gets negative numbers. I realize those things come from different parts of the brain, but I was really like, "Whoa, girl!"

Sir, it's not an offence to let your cat eat your bacon. Okay? And we don't arrest cats, I'm very sorry.
My older brother and I taught our younger brother about negative numbers when he was in second grade. He grasped the concept pretty easily.
