Growth mindset is something I've been working on with my kids for a long time, though. We even have a tradition of applauding when someone makes a really good mistake.Laura Hawkinshttps://www.blogger.com/profile/09821023948980936380noreply@blogger.comtag:blogger.com,1999:blog-684256519801046819.post-11656526966439420772013-10-23T18:12:29.313-07:002013-10-23T18:12:29.313-07:00I saw the MSMathChats and got a little bit jealous...I saw the MSMathChats and got a little bit jealous. I found alg1mathchat, but I haven't stumbled upon any other high school level chats yet. Still looking, though!Laura Hawkinshttps://www.blogger.com/profile/09821023948980936380noreply@blogger.comtag:blogger.com,1999:blog-684256519801046819.post-50135087130658139712013-10-19T12:49:34.197-07:002013-10-19T12:49:34.197-07:00Hi there!

Smal l twitterverse :) It was an awesome tweet! It sounds like you also took the How to Learn Math Course and are trying to create a growth mindset in math class. My department made posters that say "It's OK to FAIL....FAIL = First Attempt in Learning". I also like your pictures. Makes me feel like I need a snack :)Carrie Annablehttps://www.blogger.com/profile/12116223847369125699noreply@blogger.comtag:blogger.com,1999:blog-684256519801046819.post-5436963626207312302013-10-19T12:08:40.517-07:002013-10-19T12:08:40.517-07:00I love the hashtags too.

Your method would indeed be...Thanks for watching! <br /><br />Your method would indeed be one way to factor y^2 +2y. You'd get a rectangle with that area, a length of y and a width of y + 2. But for this problem, since the area was divided by 2, we already knew the "length" would have to be 2. But then you get stuck with where we were at 0:03. The only way to resolve the issue and keep the integrity of the model is to go 3D. And then you get a "width" of y^2 + y, which is the answer to the division problem!Laura Hawkinshttps://www.blogger.com/profile/09821023948980936380noreply@blogger.comtag:blogger.com,1999:blog-684256519801046819.post-19017550334654468132013-10-19T10:37:46.741-07:002013-10-19T10:37:46.741-07:00I really like the video - thanks for sharing!
B...I really like the video - thanks for sharing! <br /><br />Before I watched the video, when I visualised it, I didn't imagine a 3rd dimension. I had two y^2 squares one below each other and two yx1 rectangles one below each other - why did you decide to go 3d? joiningupthemathshttp://joiningupthemaths.wordpress.com/noreply@blogger.com
