Looking forward to the next one already.

Here are the jokes:

- I used to train racing snails. One day, I took the shells off to see if they’d go faster. It didn’t really work and, if anything, it made them more sluggish.
- I can’t stand Russian dolls. They’re so full of themselves.
- I’ve always wanted a job putting up mirrors. It’s something I can really see myself doing.
- An ex-student of mine said he’d been doing a building course and could build me a ‘wishing wall’ in my garden. I thought, bless him. He means well.
- Here’s a site for sore eyes: http://www.conjunctivitis.com
- Someone complimented me on my driving the other day. I got back to the car and there was a little sign saying “Parking: Fine”, which was nice of them.
- My cat’s a genius. I asked her what 2 minus 2 was and she said nothing.
- Somebody stole my mood ring. I’m not sure how I feel about it.
- Cheer leading exams are easy. You go in and shout “Give me an A”.
- I’m very good at maths. I understand 110% of it.

After being rated 324 on a scale of 0 (not funny) to 4 (hilarious) here are the average results:

(The one on the end is the 110% joke.)

If you’d like to see the raw data and the jokes in a word document, then there’s a link to a dropbox file here.

I got my students to rate the jokes themselves (they seemed to conclude they weren’t very funny). Then, they compared their ratings with the average score for each joke from the internet. Students also compared their ratings with another student to see if they had similar senses of humour or not.

This tortoise has irregular hexagons on its shell. (Fun fact – tortoises shells aren’t watertight. If they get in deep water, they fill up and will sink. Tortoises are not turtles.)

Tortoise

This lovely carpet python and lizard both have hexagonal skin! (I was disappointed that the python wasn’t 3.14 metres long.)

As I was looking at the turtles, I was struck by these numbers and their potential for a maths class.

Somewhat frighteningly, **17.4 tonnes** of live turtles are shipped from Vietnam to China every day. If the turtles are **2kg each**, how many is that? How many of our classrooms would this many turtles fill up? Would it fill the school hall? How many of them is this in a year?

What assumptions are we making in modelling these?

Is 17.4 tonnes a day plausible? How many turtles are there in the world?

It can be (legitimately) that they are given very little space and ‘we’ aren’t concerned about their comfort levels.

**Nice numbers**

We discussed the idea of some numbers being ‘nicer’ than others. This really is a bit a weird topic and hard to describe but I think we all have an inner feeling of which numbers seem nice. You may have heard someone say, “ooh, let’s make it a nice, round number” for example. Alex Bellos has written about how people have favourite numbers and that the most popular choice is 7. My current favourite number is Belphegor’s Prime:

**1000000000000066600000000000001**

**3s, 6s, and 9s**

I also talked about taking a string of 3s (or 6s or 9s) and squaring it. See what happens.

33333² = 1111088889

**15* kievs**

We talked about when 15 = 16 or when 15 is a square number:

Some questions that came from twitter:

- What are bounds for the radius of a kiev?
- What’s the minimum number of kievs you might get in a bag?
- How can they be so precise about the amount of salt in a kiev that seem to vary in size?
- If the * is a power, what does it equal?
- What percentage extra did I get?
- How many chickens were harmed to make this bag?

**A game or two (Two. It’s definitely two.)**

I also made a hash of describing a game called Areamaze. Evelyn did a better job of describing Euclid, the Game. Try them yourself!

Thanks for listening. If you’d like to be on an episode, let us know.

Dividing by Decimals by amurra8827

This is a very good resource. It has a lot of questions to do with decimal division and explores it in a sensible, understandable way.

Year 7 Place Value by mathshub

An exceptionally well planned power point with a clear level of deep understanding and thinking involved.

C1 and C2 revision cards by mrsmorgan1*

Absolutely excellent for revision. I can’t really believe I haven’t seen something like this before!

**I had credited this resource to someone else but they appear to have simply taken Jo’s resource and uploaded it as their own. I’ve removed my review for them and reported the resource.*

They also inspired me to write and upload two new resources of my own:

Yes, that’s a custom made t-shirt:

The idea was mine and the design and printing was by Extra Mile Printing.

And the back….

As it happens, my daughter had to design and make a Christmas hat for her last day so I helped with the star:

Hope you like the costume and have a great Christmas break.

***** 5 Star resources *****

Between the lines (UndergroundMathematics)

A challenging puzzle that will really push your KS5 and top end KS4 to think hard about their understanding of straight line graphs. Well structured with hints and prompts throughout.

GCSE Maths 10 minute assessments (manisha2011)

This is pretty self explanatory really. I liked the simplicity of this resource and the range of topics covered.

**** 4 Star resources ****

Commenting on Election Data – Core Maths (ecrae)

This is a resource aimed at the Core Maths (level 3) qualification but there’s nothing stopping you slipping it into the gcse course.. It’s a good resource as it makes students interrogate the data given and draw valid conclusions. I like the way it could be used to make students think hard about newspaper headlines.

GCSE Revision/End of term maths pub quiz (chris_cooper_25)

There are a lot of maths rounds covering a spread of topics. These are interspersed with some non maths rounds as well. It would probably have 5 stars except that you’ll need to update the general knowledge round and work out your own music round (or just abandon those ones).

Edexcel S1 Revision clock (Japleen Kaur)

Based on the recent wave of revision clock resources, this is set up for the edexcel S1 course. It’s a great idea and because A level questions are longer, it adapts the format to allow longer questions extra time by having two or more sections of the clock.

*I hope you’ll check these out and maybe give them your own reviews too.*

A simple 4×4 grid.

Each one has a calculation to be done (choose from arithmetic or negatives).

Only two are shown at a time for 1 sec at a time.

There are other starters to try out too. Thanks to Vic for sharing this.

I make no secrets about not being a fan of the mechanics aspects of mathematics. I love statistics and decision maths while I’m beginning to like pure maths more. I do think that non-mathematicians don’t really understand how different the various areas of maths are and I was wondering how similar/different this is to the sciences. I don’t think many people would expect someone with a biology degree to be very comfortable teaching A level physics or chemistry and I think there is a parallel within the maths areas. While I do think that some of the skills are transferable (as I suspect they are in the sciences), simply being good at teaching mechanics would not automatically make you good at teaching statistics. They definitely are not ‘just all maths’. With the changes to A level maths, I may well have to try and pick up some aspects of mechanics but I maintain it would be better to have people who are specialists in the areas they’re teaching.

I’ve emailed to ask about the raffle tickets. I’ll write a blog post about it when/if they reply.

The mathsjam annual conference is coming soon (12th and 13th November) and I am now booked to go. Hurrah.

Here is a link to a post where I give a little more detail about the maths books I bought.

I think that’ll do for now. Perhaps you should go and listen to it.

I’ve collated and refined the results from the survey along with the experiences of my faculty into a structured powerpoint presentation. It was used in an hour session with mostly year 12 students. I consciously included some interactive bits and tasks to do and a couple of different presentation style so it’s not all just listening to me talk. Here’s a link to the ppt and you’re welcome to use/adapt it as you wish. Thanks to all the people that answered the survey and I know a lot of you will be interested in seeing the results.

If you take a look, you’ll notice that the last part is a wider reading list, aimed at anyone that wants to broaden their maths understanding or general interest, perhaps with a view to mentioning it in UCAS personal statements. It is obviously non-exhaustive but here’s the list for ease of reference:

**Books**

__Why do buses come in threes?__Rob Eastaway & Jeremy Wyndham__Professor Stewart’s cabinet of mathematical curiosities__Ian Stewart__Cracking Mathematics: You, this book and 4,000 years of theories__Colin Beveridge__1089 and all that__David Acheson__Flatland – A romance of many dimensions__(free ebook) Edwin Abbott__Fermat’s Last theorem__Simon Singh__How to cut a cake__Ian Stewart__The Simpsons and their Mathematical Secrets__Simon Singh__The man who loved only numbers__Paul Hoffman

**Podcasts**

**On the internet**

As I was buying a book for my son (Number Quest – more on this another time) I stumbled across an eBay shop that had lots of maths books for sale pretty cheaply. Now, they also had an offer on of “buy 40 books, get 50% off”, and, like a TV with a broken volume control, you can’t turn that down can you?

I picked out some for myself:

Some that I’m going to take in for students to borrow:

And there was only a minor mishap as I tried to buy a couple of copies of Alex Bellos’s book, ‘Alex through the looking glass’:

I don’t suppose anyone wants a snooker book do they?
