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

    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!!

    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.

Help Students Learn to Manage Their Time

In my early years of teaching, I didn't always know what to say when students told me they didn't have time to do their homework (other than something like, "You must have had some time between 4:00 and 9:00!). There were all kinds of reasons - they had sports practice or a lesson, or they had to go to their brother's or sister's game/practice/event of some kind; or their parents took them shopping or out to eat. At that time I had one child (who was 2 when I started teaching), so I didn't have the experience from a parent's point of view of making sure I was getting my kids to their activities, getting done all the house-related things, and also making sure they were getting their homework done. This made it a little difficult for me to relate to the students' situations, but I tried to help them think about how much time they did have to do their work. Being involved in activities definitely reduces time for schoolwork, but it doesn't mean t...

Beach Ball Math Fun

I don't think I can fit all 12 beach balls - but I may try! I know lots of people use beach balls in the classroom, but I haven't used them in such a long time that I thought I'd share my excitement about finally getting around to getting new ones! I have a little bit of a beach theme in my room this year, so that motivated me to get some beach balls again. I ordered a pack of 12 and am writing different math skills practice on them - so far I have multiplication facts, exponents, fraction/decimal conversions, and common measurement conversions. I have 12 beach balls to fill with math, so I need to decide on more topics. I think I'll do square roots, division facts, math vocabulary...I need to keep thinking:-) Palm tree w/math practices - word wall will be to the right. Our math classes aren't that long, but I figure I can squeeze in 5 minutes at the end of class once or twice a week to toss the beach balls around for some quick facts. With so many differ...
