Of course, that was after I had my turn playing with the system (I hadn't seen desmos before).<br /><br />FYI, if you want to embed animations into your blog posts, you can use iframes, like this: <br /><iframe height="1000" src="https://www.desmos.com/calculator/3x8xwsw7hp" width="1000"> </iframe><br /><br />You often have to adjust the height and width parameters.

Math and chess do have some interconnection because both of these require brainstorming. A good chess player is expected to perform better in mathematics and this has been proven many times.<br />Also, i would like to appreciate the work that you are currently doing. I myself teach mathematics try to see different methods that can help the students to grasp the concepts in easy way. We give <a href="http://sunnyvalemathchess.com/" rel="nofollow">math and chess lessons in sunnyvale</a> and are going to make use to some tactics to implement.<br />Regards:<br />LarysaLarysa Yoasthttp://www.blogger.com/profile/10679430017293166175noreply@blogger.comtag:blogger.com,1999:blog-5303307482158922565.post-78878556025218463182014-09-15T20:50:07.612-07:002014-09-15T20:50:07.612-07:00Bowen's link takes you to a page with puzzles ...Bowen's link takes you to a page with puzzles that are somewhat similar to Paul's.

For example, even double entry bookkeeping was a major innovation!<br /><br />I've started teaching a little programming class at my child's school. Basically, my approach is to combine these two ideas. I show them some cool things and then encourage them to play. Mostly, this involves not standing in their way or removing some minor obstacle or misunderstanding that is blocking them. The big obstacles, though, they get the joy and satisfaction of tackling themselves.Joshua Greenehttp://www.blogger.com/profile/11702319994021721608noreply@blogger.comtag:blogger.com,1999:blog-5303307482158922565.post-56172147515793086012014-09-04T05:13:25.911-07:002014-09-04T05:13:25.911-07:00And you're welcome to email me if you'd li...And you're welcome to email me if you'd like this as .doc or .pdf.Sue VanHattumhttp://www.blogger.com/profile/10237941346154683902noreply@blogger.comtag:blogger.com,1999:blog-5303307482158922565.post-78057708689496247442014-09-04T05:12:23.082-07:002014-09-04T05:12:23.082-07:00I've fixed the post.

Besides being a good source of psychological and pedagogical analysis the book contains the description of the way the classes were conducted and the materials used. I only wish one day the author looks at the current market and provides readers with his view on what we can use now for similar purposes. I would have liked to see what additional MODERN books he recommends, what he thinks of electronic devices and apps for kids etc. Some aids the author used in his book are not available any more and some of the books he read to the kids are a rare find as they are out of print. However most information in the book I am able to use and my kids are enthusiastic each time I give them a task from the book.

It might help to give students a bit of a recipe for how to respond, for example:<br />(1) write down why you think the problem is wrong/missing information/has conflicting information/etc<br />(2) If you are missing information, can you work out a case where you fill in the missing data?<br />(3) Can you think of another way to salvage the question?<br /><br />Also, I think the best lesson about attending to precision is when they see examples that aren't precise and then see the consequences of that imprecision. In improv comedy you can experience this viscerally: students pretend to give each other blind offers (handing a mimed, empty box or shouting and pointing "My goodness, what's that?!") and then the next student has to continue the scene. Students who get vague offers (as in my examples) will almost always feel frustrated that the whole burden has been thrust on their shoulders. Students who are given more information ("my goodness, what's that elephant doing here?") have a much easier time continuing.Joshua Greenehttp://www.blogger.com/profile/11702319994021721608noreply@blogger.comtag:blogger.com,1999:blog-5303307482158922565.post-11557353552638825522014-08-05T22:57:59.517-07:002014-08-05T22:57:59.517-07:00You promised to bust myths 1 and 2, but only expli...You promised to bust myths 1 and 2, but only explicitly address myth 1.

No one is losing points on a standardized test that could be high-stakes, based on the problems you write. And if you tell your students they get extra points for finding your mistakes, then it's a win-win every time you make a mistake. ;^)<br /><br />Whereas this was made by a big publisher, costs someone lots of money (in my program I believe its coming from a grant), and because it's coming from 'above', the students might think it knows more than I do. I think I can get past that quickly, and may take my own advice. Cheers and possible rewards or awards for students who find similar mistakes in the tests. Let's make it a detective game, which is more my idea of what math is than these tests.Sue VanHattumhttp://www.blogger.com/profile/10237941346154683902noreply@blogger.comtag:blogger.com,1999:blog-5303307482158922565.post-67528232708906817662014-08-01T16:41:20.054-07:002014-08-01T16:41:20.054-07:00Really interesting.

As a middle school teacher who writes a good chunk of my own curriculum (read: questions students answer, problems students solve) because I don't have one I like to work with, I catch these types of mistakes in material I create all the time. I often compensate by being descriptive (shown below are a parallelogram and a rectangle) but it's not the same as a well-written set of textbook problems that fits the scope and sequence you are teaching. If we want students to truly Attend to Precision, we need to Attend to Precision ourselves... definitely something for me to work on, either in writing or finding great materials.fivetwelvethirteenhttp://fivetwelvethirteen.wordpress.com/noreply@blogger.comtag:blogger.com,1999:blog-5303307482158922565.post-32080062021083308052014-08-01T16:07:25.713-07:002014-08-01T16:07:25.713-07:00Neither I nor the students are paying for it, than...Neither I nor the students are paying for it, thank goodness.
