One of my colleagues once had a bulletin board with gravestones on it. Every time her students uncovered a misconception she recorded it in her "math graveyard." Not really in my comfort zone, but it worked for her. Some of the ones that drive me nuts as a sixth grade teacher, besides multiplying makes it bigger, are: "bigger number in the dividing house", bigger number on top to subtract, and squares are not rectangles. Today the misconception we were rooting out was about rounding. It goes something like keep the numbers in front the same, adjust the underlined number, and change the numbers behind to zero. Well, we were rounding decimals - so we hit something else that "used to be true."<br />Looking forward to reading more and sharing with my colleagues.Anonymoushttps://www.blogger.com/profile/15555398878346747345noreply@blogger.comtag:blogger.com,1999:blog-812794395259173668.post-30495138753116220042013-12-03T19:03:57.191-05:002013-12-03T19:03:57.191-05:00Thanks all!

The idea of doing the most powerful operations was a new one to me too. Interestingly the misconception of "multiplying makes things bigger" is one we had listed for a potential new section called "Things that used to be true" and yet I fell prey to it myself. Fixed now.

As a sixth grade teacher who is always trying to undue misconceptions - multiplying makes things bigger, subtracting makes things smaller - the sentence about exponents increasing at a faster rate than mulitplication caught my attention. I wonder if you might want to say "increases or decreases" instead. When the number is a proper fraction and you use it as a power or factor it isn't increasing. I am very interested to know what you think.Anonymoushttps://www.blogger.com/profile/15555398878346747345noreply@blogger.comtag:blogger.com,1999:blog-812794395259173668.post-35061364906231316662013-11-30T13:09:09.249-05:002013-11-30T13:09:09.249-05:00Really nice work.

I try to avoid teaching tricks, but them my students read the textbook and pick them up anyway :(<br /><br />I found some typos:<br />page 21 (5.3 Nix: Cancel): missing two "-symbols: at the end of the sentence "cross-out stuff by magic" and after |cancel" in the fix section<br />page 22 (5.4 Nix: Take/Move to the Other Side) missing "-symbol at the end of "We add the opposite to both sides. That gives us zero on the left and leases +4 on the right." in the fix section<br />page 24 (6.1 Nix: what is b?)
