no it's at least 1 point got stating the 15 (2nd to last item on the rubric).  Original Message  From: <precopio@nycap.rr.com> To: nyshsmath@mathforum.org Cc: "Roberta M. Eisenberg" <bobbi@alumni.nd.edu> Subject: Re: algebra regents 2011 Date: Mon, 20 Jun 2011 11:19:13 0400
I am still fuming over question 35. I had many kids who did not actually write an inequality or an equation, but they Added 20 and 15, then subtracted from 45, then divided by .65 and then stated the correct answer of 15. According to the rubric this is zero points?  "Roberta M. Eisenberg" <bobbi@alumni.nd.edu> wrote: > Unfortunately that is not correct.
