yes a lot of info there thanks ,,,but common core is destroying the kids...it is the dumbing down of America. I remember the first time my daughter brought home some math problems the common core style. She was having a hard time bc it made no sense. I sat down to help her and was appalled on what they are teaching. I showed her the real way to do math and she said it made sense and this was easy. The teacher did not like the way she was doing it because it was not how she was shown so she was going to fail her, right up until the time DAD went to see the teacher. Well the teacher started to explain this is not how she was shown. I stopped her mid sentence and said "Look you are going to tell an aircraft engineer how to do math?? I dont think so". I asked her what were her qualifications to teach math. She said i am a certified teacher. I say "That is not what i asked." I told her you can get your degree in finger painting and call yourself whatever you like. Your job as a teacher is to teach and if you cant make it make logical sense to the kids you are in the wrong profession. i then told her if you fail my daughter because she is smarter than you, I pity the outcome you will be dealing with me and you wont like it. Funny how my daughter passed with flying colors. Common core is still bullshit....
