Anyone dealing with this common core bullshit? Math is extremely simple for me (I was an engineer) however my kid's teacher just asked me to come in for a conference since she was "struggling" and using a "strange" method for subtraction. I almost lost it. I was working with my daughter because I saw her tests were weak. I showed her how to borrow numbers and it was so easy for her. Started passing all of her tests. At the conference they said she can't do that and they recommend a tutor, I told her my background and it quite easy for me to teach my daughter. She said no you need to know common core and the specialized version that we teach in our city. Then she went on the say, the problem is that no one else knows hey is old enough to teach it to her!!!!!!! I live in one of the top school districts in the country and this is the bullshit test taking knowledge that they are teaching.
