  1. I agree with you 100%. This has been a big problem for us in the middle school when students come in from elementary.

  2. Agree!!! When I read the title of your post...I thought you were going to support the butterfly method. So glad you are not an advocate!!

  3. Thank you! I am a high school teacher and the kids want to "butterfly" every fraction they see which doesn't work when they need to get a common denominator with several fractions that now have variables mixed in. They really need to know what a common denominator is and how to find one. I really didn't understand what the kids were trying to do with the "butterflys" because even they couldn't remember the whole thing to show me what they had been taught.
