### 5 Maths Gems #84

Welcome to my 84th gems post. This is where I share some of the latest news, ideas and resources for maths teachers.

1. GCSE Revision Checklists
Thanks to @mrchadburn for sharing his GCSE revision checklists for both Higher and Foundation tier in his post about GCSE preparation.
And for similar information in a totally different format, Miss Banks (@MissBanksMaths) has shared Higher and Foundation GCSE checklists, organised like mind maps.
For more resources for the fast approaching GCSE exams, see my 9-1 revision resources post (the most viewed post I've ever written!).

2. A Level Resources
Thanks to Sandra D (@mathsbox1) for creating a set of free AS Pure revision notes for the new A level.
Joe Berwick (@Joe_Berwick) has also been busy creating some excellent A level resources which are available on TES, including detailed notes and examples for the new Year 12 statistics content. These are written for students but might also be helpful for teachers who are teaching this content for the first time.

Finally, if you've got any students preparing for STEP this year then do check out the fantastic STEP Support Programme from the University of Cambridge.
3. Rich Tasks
Mr Knowles (@SK18Maths) has shared a number of activities on Twitter. This one is on sequences. Follow Mr Knowles for more tasks like this.
4. Variation Theory
You may have heard a lot about variation theory over the last couple of years. To use it correctly in the classroom and create appropriate resources, it's essential to have a strong understanding of the underlying principles. Naveen Rizvi (@naveenrizvi) has written an excellent blog post 'Resourcing: Applying Variation' that really clarifies how variation theory works - it's well worth a read.
5. Addition Pyramids
I observed an interview lesson in which the teacher used a classic starter activity. It's really simple and engaging, and works well at any age. It looks like it may have been based on this Nrich task.
I tweeted this activity and had lots of replies suggesting adaptations involving manipulatives, algebra and probability. A lot of people used this activity after I tweeted it and reported back that it worked really well. It made it to Mexico too.
I enjoyed reading Michael Jacobs'‏ (@msbjacobs) lovely blog post about similar puzzles that he's used with his students.

Thanks to Miss Banks (@MissBanksMaths) who has shared some free resources for this activity on TES.

Update
In case you missed them, here are my latest blog posts:

If you enjoyed my post about Elementary Algebra for Schools, you might be interested in looking through the online textbook 'Elementary Arithmetic' to see how primary mathematics was taught a century ago.

If you're involved in the delivery of Core Maths or A level maths then I'm sure you'll be interested in this week's announcements regarding financial incentives for schools to increase uptake. I have mixed views on this!

The Kettering maths conference is next weekend! I'm looking forward to seeing everyone. I'm also really excited about BCME which is only one month away now.

I'll leave you with these puzzles from The Mathematical Gazette, one of the excellent publications of the Mathematical Association. The Student Problems will be made publicly available going forward. Prizes are available! The deadline for these two puzzles has passed but look out for the next set soon!
