I agree with you 100%. This has been a big problem for us in the middle school when students come in from elementary.
ReplyDeleteSo glad to hear it isn't just me! Thanks for sharing!
DeleteAgree!!! 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!!
ReplyDeleteNo, definitely not an advocate! Glad to hear that others agree:-)
DeleteThank 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.
