You've ...Thanks ver much for our comments Matt. You've got me thinking about situations in higher topics when this method would not be the most apt and also when 'our' method might not be the most apt: i haven't got the answers yet but I am thinking;-)! As for showing your working out I certainly am in favour of this being shown clearly as in your example especially when students are beginning to learn these techniques. That being said, once this has been mastered (as this student clearly has) I myself feel that the work he has shown is sufficient. But I would be interested to know what other people think.<br />Thanks again, <br />MikeMikeJacobshttps://www.blogger.com/profile/03272175755461671596noreply@blogger.comtag:blogger.com,1999:blog-5994368862134076388.post-67881025509622347832017-09-14T02:35:17.558-04:002017-09-14T02:35:17.558-04:00Although alternative methods are of merit & in...Although alternative methods are of merit & interest (as long as pupils are correctly applying inverse operations) ... I would discourage pupils (like this one has) from reducing their number lines of working ... this is how errors may occur with + or - signs/operations. Also a method that undoes the equation in the order in which it was constructed is IMHO best practice. Bear in mind that these alternative methods may become their method of choice and when we move onto problem solving or into higher topics (eg solving simultaneous equations) these alternative approaches may not be the most apt ... which is why I recommend encourage pupils master the method I supplied an image of ... which you have kindly reproduced.
