In Gems 51 I wrote about the brilliant game Is this prime? from @christianp. My colleague Greg currently holds the Glyn Maths Faculty record in this game (51 – after a lot of practice!). We’re a competitive bunch and we’d all love to beat him! This week more games have been shared on Twitter, for the amusement of both maths teachers and students.
Hannah Fry (@FryRSquared) shared guessthecorrelation.com. In this retro-style game players have to guess the correlation from a series of scatter graphs (between 0 and 1, where 1 is perfect positive correlation). I’m better at this than the prime game! I might use it when I next teach S1 to add a bit of excitement to my PMCC lesson…
Huge thanks to Colleen Young (@ColleenYoung) for sharing an amazing resource for A level students. MadAsMaths.com contains loads of helpful resources. I am particularly excited by the practice papers for C1 – C4. These are very useful for students who have already completed all the past papers, especially students aiming for a top grade.
Read Colleen’s post for full details.
3. Is That a Big Number?
IsThatABigNumber.com is a new website that may be worth exploring. It aims to put numbers in context, promote numeracy, share number facts and develop number sense. You can enter a number and get some interesting comparisons.
The quiz is fun too.
4. A Problem
I enjoyed this problem – it was shared by @Five_Triangles.
The green triangles are equilateral and you need to find the area of triangle A.
5. GCSE Revision
The maths department at Saint Aidan’s (@SaintAidansMath) regularly tweets GCSE questions for its students. Its website is worth exploring – it contains lots of useful resources including GCSE revision cue cards which students can print back-to-back to quiz themselves and their friends.
I recently wrote a post about the upcoming changes to A level – if you’re an A level teacher do have a look at both my post and Tom Bennison’s (@DrBennison) follow-up post.
Finally, this English/US grade/year classification (created by Kaplan and shared by @AceThatTest) is helpful. I sometimes find it hard to navigate US resource websites (like the excellent Mathematics Assessment Project) because I don’t know age equivalences. I also read a lot of American blogs, so this will be useful for future reference.
