^{st}gems post. This is where I share some of the latest news, ideas and resources for maths teachers.

**1. Linear Graphs**

Related to this, check out this awesome task shared by Tim Honeywill (@HoneywillTim).

It looks like some maths departments are being asked to produce knowledge organisers as part of a whole school policy. It's not clear whether they are as useful in maths as they are in other subjects, but if you're in a school where you've been asked to produce them for every maths topic then you're faced with a mammoth task. To avoid duplication of effort across schools, you might find this set of knowledge organisers a useful starting point. Also, check out the set of Year 8 knowledge organisers shared by Delta Trust, and these lovely knowledge organisers shared by Nicola Whiston (@whisto_maths). Nicola will continue to add her knowledge organisers to this folder as she makes them. They are designed around the White Rose scheme of work.

These resources can be used in numerous ways - even if your school doesn't have a policy of self-testing using knowledge organisers then you still might find this resource helpful for revision.

Nicola Whiston (@whisto_maths) has also made a learning journey for the White Rose Scheme of Work - schools following this scheme of work will find this helpful, and even if you're not following this scheme of work then it is interesting to see the way the maths curriculum has been mapped out.

The Mathematical Association has just published a book, written by David Miles, which contains photocopiable activities for A level lessons. It's selling very well - you can order now from the MA shop for £6.30 (members) or £9.00 (non-members). I will also be selling these books from the MA stand at #mathsconf22 in Manchester.

Although it's already available to buy, this book will be officially launched at the MA Conference in April, along with a couple more exciting new publications - Geometry Juniors by Ed Southall and Hooked on Mathematics by Jenni Black. Do come along to the book launch if you're at the conference.

Caroline Spalding (@MrsSpalding) shared a picture of a poster she saw in a science lab at her school. It shows etymological roots of science vocabulary.

This prompted Ben Gordon (@mathsmrgordon) to make a maths version of this which he has shared here. Thank you Ben!

Following this, Sudeep (@boss_maths) shared an amazing resource to help relate maths terms with key words from other subjects or words in everyday use.

This large (and growing) collection is outstanding. I love Boss Maths resources - they are always high quality.

I love featuring etymology in my lessons. It's great to see resources like this to help teachers develop their subject knowledge.

There have been lots of new resources shared on Twitter recently. Here are some examples.

Don Steward has published lots of new tasks, including fraction shading and order of operations with expressions.

Do scroll through his blog to see his new resources - there are many!

Andy Lutwyche (@andylutwyche) regularly shares new resources. Check out his newest Transforming Shapes Codebreaker which is bound to be popular with students (and not just because of the terrible joke!).

As always, all of these resources will be listed in my resource libraries for easy access.

Chris McGrane (@ChrisMcGrane84) shared an interesting task on negatives numbers that really got me thinking.

Emma McCrea (@MccreaEmma) tweeted about a couple of openmiddle.com tasks. I have blogged about this website before but haven't had time to explore all the tasks. I particularly like this one on index laws.

Mr Russell (@mathsDRL) reminded me about Jon Orr's (@MrOrr_geek) Polygon Pile Up activity. I know I saw it a couple of years ago and I was sure that I'd featured it in a Gems post, but I can't find it so maybe I didn't. Here it is - read the accompanying blog post for the resource, discussion, and a more difficult version.

**2. Knowledge Organisers**

**Update**

Here are my recent blog posts in case you missed them:

On Monday I visited Sheffield to record another two Topics in Depth video CPD podcasts with Craig Barton. You can check out our indices and angles in parallel lines videos if you missed them. Hopefully the next two will be published by TES soon.

My book is still getting good feedback - I am always delighted to receive tweets from teachers who have learnt something new from it.

I was also chuffed to see my book shortlisted for the Chalkdust Book of the Year 2019. You can read the Chalkdust review of my book here and vote for it here (though to be fair, all these books are awesome and deserve more votes than mine!).

I'm looking forward to two big events that are coming up soon. On Pi Day I will be in Manchester for #mathsconf22, presenting a new talk from my Topics in Depth project: Surds in Depth.

In the Easter holidays I will be presenting at the MA Conference. I can't wait for this: two nights in a spa hotel with loads of amazing workshops and plenty of entertainment.

At the MA we're really pleased that our new conference format has been so well received. Over one hundred delegates have already booked their place. There aren't many full residential places left so book now!

I recently passed a milestone of 30,000 followers on Twitter. I'm not sure there are many other females on EduTwitter who have done this and are still teaching. I'm pleased people find my account useful, and I really appreciate the support.

Finally, did you see the Joanne dress from Popsy? If, like me, you enjoy going to work (and maths conferences) in mathematical attire, then you'll like this one...
