This makes a nice topic in itself and once they have got it they will never ask you why 'flip and times' works ever again (Petehttps://www.blogger.com/profile/03127735621909243636noreply@blogger.comtag:blogger.com,1999:blog-4242439961617529545.post-71750765884845752052016-04-29T06:05:06.524+01:002016-04-29T06:05:06.524+01:00thanksthanksAnonymoushttps://www.blogger.com/profile/01023780064962157121noreply@blogger.comtag:blogger.com,1999:blog-4242439961617529545.post-20160699553799841252016-04-08T08:08:45.356+01:002016-04-08T08:08:45.356+01:00ThanksThanksAnonymoushttps://www.blogger.com/profile/01023780064962157121noreply@blogger.comtag:blogger.com,1999:blog-4242439961617529545.post-39830215486929407022015-08-10T14:31:18.511+01:002015-08-10T14:31:18.511+01:00Hi.

Perhaps there should be an annual INSET for local secondary and primary schools to collaborate/share ideas, or opportunities for secondary teachers to visit local primary schools to watch lessons (and vice versa).

I enjoy drawing shapes to demonstrate operations with fractions (usually rectangles), but do need to use more of the paper folding (I've been looking at using more 'foldables' recently).

But because we assume they have that understanding, we don't spend as much time on fractions as we should.

Many pupils don't know this when they arrive at secondary school and I fear that the use of procedures and mnemonics in isolation means,that some leave secondary school without ever knowing what they are. Once pupils understand what they are and their nature then equivalent fractions becomeCavhttps://www.blogger.com/profile/08497166692282461180noreply@blogger.comtag:blogger.com,1999:blog-4242439961617529545.post-38130360816927630642014-08-12T21:37:50.592+01:002014-08-12T21:37:50.592+01:00Love it!
