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

**1. World Cup Box Plots**

Thanks to Southborough Maths (@Mathsteam1) for sharing these box plots created by @johnwmillr. They show the distributions of height by position for players in the World Cup. They make for great discussions with students, and provide a nice demonstration of how box plots can help us make comparisons.

I've been using a similar set of graphs for years, every time I teach box plots (see my post on teaching box plots for more on this). It always goes down well.

**2. Variation Theory**

Last week Craig Barton launched a new website packed full of sets of well written questions for intelligent practice. Do check out variationtheory.com if you haven't already seen it.

'Mixed Bases' by Joe Berwick |

Like Craig's other resource websites (SSDDs, Venns and Diagnostic Questions), you can submit your own resources for inclusion on this website.

**3. Fractions**

Thanks to Berkeley Everett (@BerkeleyEverett) for sharing this animation. This can be found, along with loads of other great animations, on the Math Visuals website.

**4. Compound Shapes**

Thanks to Mark Ives (@MarkIvesTeach) for showing us how he used Numicon to support students in identifying the lengths of sides in compound shapes.

**5. Coordinates Problems**

Thanks to Dave Taylor (@taylorda01) for a sharing a set of challenging coordinates problems (see this tweet and this tweet) . Here are a couple of examples:

**Update**

Do maths teachers all say things in the same way? At the Tweet Up in Manchester last weekend, I recorded a group of teachers saying words that I've heard pronounced differently by different maths teachers. I've picked three of these words for the first video from my pronunciation project:

Thank you to everyone who took part! It may not be the most exciting video ever but I think it's really interesting that students hear different things from different teachers.

**Here are a few other things you might have missed recently:**

- ThinkMaths (@thinkmaths) are doing their annual giveaway of maths goodies - the 'Exciting Maths Toys for Excited Maths Teachers Mailout' - sign up now!
- I'll be taking part in the Big Internet Math-Off in July - and I'd really appreciate your support!
- Check out this great post from Alex Cutbill (@intersectarian) about the definition of 'power' in maths. This is what I was talking about in my conference session last Saturday.
- Do check out the excellent set of surds questions from Gillian Matthewson (@gmathewson1) on her new blog.
- The Nuffield Foundation report "How do shortages of maths teachers affect the within-school allocation of maths teachers to pupils?" is worth a read.
- I recorded a podcast after the JustMaths conference with Craig Barton which is now online - you can listen to it here. It's only half an hour!

It's all been a bit crazy lately. Next week I have an AQA Expert Panel Meeting, the BBO Maths Hub conference, a TTRS Rock Wrangle trip, and prom. Then I can relax!

I'll leave you with this lovely factor tree puzzle from Sarah Carter (@mathequalslove), inspired by @HaroldReiter.

a=2, b=1, c=0, d=7, e=3, f=5, g=6.

ReplyDelete210 = 7 x 30 = 7 x 5 x 6 = 7 x 5 x 2 x 3
