Blogs

• “Stretching Practice” from  @mathsjem ~ Jo linked this last week in response to a #mathsTLP question about practice problems for high attainers – there’s lots of great stuff here I’ll be checking out to stretch my Y10 group this year.
• “An apology from the DfE” from @MichaelT1979 via @Sue_Cowley ~ This really made me appreciate just how tough primaries have it this year!

Resources

• One incorrect simplification from Median (via @mathsjem) ~ A really nice probing/challenging set of problems on algebraic simplification.
• Vectors resources (via @DocendoTim) ~ There’s a large selection of stuff here for teaching vectors.
• A rough guide to new GCSE from @Ms_Kmp ~ A good infographic showing GCSE changes and comparisons; this might be useful for both pupils and parants and serve as a useful reminder for teachers.

Other awesome stuff
