So what&...Nicely done Michael. I'm impressed. <br /><br />So what's your take on this teaching methodology? Does it legitimately train critical and creative thinking or is it just the product of self-important education bureaucrats and academics in government trying to justify their jobs?Edhttps://www.blogger.com/profile/01235046826421680852noreply@blogger.comtag:blogger.com,1999:blog-26061284.post-84419205499791314602014-03-03T23:50:59.469-06:002014-03-03T23:50:59.469-06:00It took me a few minutes, but I understand how thi...It took me a few minutes, but I understand how this works:<br /><br />It starts with the original problem 32-12, which is 20. This problem works backwards. It asks the question, "from 12, what do we add to reach 32?"<br /><br />Then it breaks that question down into simple math problems:<br /><br />1) Starting from 12, add 3 to get 15<br />2) From 15, add 5 to get 20<br />3) From 20, add 10 to get 30<br />4) From 30, add 2 to get 32<br /><br />Now you sum the numbers we added (on the right side of each equations: 3, 5, 10, 2 = 20<br /><br />I tested this against a few other subtraction problems and it works consistently:<br /><br />43-13<br />-------------<br />13+ 2 = 15<br />15+ 5 = 20<br />20+20 = 40<br />40+ 3 = 43<br />=30<br /><br />55-20<br />------------<br />20+30 = 50<br />50+5 = 55<br />=35<br /><br />62-16<br />16+ 4 = 20<br />20+40 = 60<br />60+ 2 = 62<br />=46Anonymoushttps://www.blogger.com/profile/03825070270628748455noreply@blogger.comtag:blogger.com,1999:blog-26061284.post-36294727575475554002014-03-03T11:04:54.629-06:002014-03-03T11:04:54.629-06:00Ed,
There are standards and then there is a method...Ed,<br />There are standards and then there is a methodology. I am not against standards which will allow all States to be measured against, well, a standard. The sticky part is whose standards are they? I cannot see a way where politics will not commandeer the process subverting any genuine conversation about what our young human capital needs to know to be competitive in the world.<br /><br />I am against the "new math". The old math put men on the moon and help the USA prosper until our progress was checked by political correctness. There is the baby d there is the bathwater. One goes, the others stays (and does math homework).davidnoreply@blogger.com
