A Mathematical Egyptian Tomb Mystery?

128 Angle ProtractorsIs the world’s oldest protractor sitting in a museum in Turin?

Physicist Amelia Sparavigna thinks she has solved the mystery of a wooden box that was found over 100 years ago in the tomb of an architect from ancient Egypt, but is her theory correct?

New Scientist has a nice article with a photo of the box and some diagrams showing how it could have worked. Why not head over there and take a look for yourself?

Touched: A new look for

ipod touchYou may be reading this and thinking ‘What new look?’, but if you are accessing the site using a handheld device such as an iPod Touch or an Android phone, you should be seeing something very different.

I’ve added a new plugin that displays a different version of the site to mobile devices. If you have any feedback or if you encounter any problems, please let me know.

If you don’t like the mobile theme, it’s easy to go back to the standard version of the site, just scroll down to the bottom of the page and turn the mobile theme off.

The Learning Zone is now online!

learnIt’s taken a while, but I’ve finally added some content to the Learning Zone on this site.

Most things have now been transferred from the old site; I expect to finish that process within the next couple of days.

My next priority will be creating materials and finding links for the GCSE revision pages for the new module exams.

That means some other tasks will remain on hold – including the next phases for Measure Island and the Beginner’s Guide to Trigonometry. Both of these are online, but aren’t ‘complete’. I’m hoping to add some extra activities to these later on this year.

Easter Egg Hunt 2011

Easter EggAre you a Y7 or Y8 student at Dronfield Henry Fanshawe School?

Do you like Easter Eggs?

You might like to try the Easter Egg Hunt – there are lots of eggs to be won!

‘Hidden’ on this website are a dozen pictures of Easter eggs like this one. When you find an egg picture, click on it to reveal a puzzle or a problem to solve.

Can you find all the eggs? How many can you solve?

Get an entry form from your teacher, or download one by clicking here. Make sure you hand your entry form in by 3:30 on Monday 11th April

You don’t have to solve every puzzle to win a prize. There are prizes for the best entries from each year group, plus lots of prizes for runners up.


Sorry – but only Y7 and Y8 students at Dronfield Henry Fanshawe School can enter the competition.

Update 1: The DHFS Easter Egg hunt has now finished, prizes have been given out (and probably eaten by now).

Update 2: Easter is over, so I’ve removed the eggs that were ‘hidden’ on this site. If you want to try the puzzles just for fun, use these links:

Can you believe your eyes?

This YouTube video seems to show a working version of M.C. Escher’s famous impossible waterfall painting. If you look carefully, you can see a copy of the painting in the bottom right hand corner of the video.

What do you think?



(PS – apologies for the adverts on the video – they are put there by YouTube – I can’t control that!)

Happy New Year!

Happy New Year! I hope 2011 is a happy and successful year for you.


By the way, did you know that 2011 is a prime number?

It is also the sum of eleven consecutive prime numbers:

157 + 163 + 167 + 173 + 179 + 181 + 191 + 193 + 197 + 199 + 211 = 2011


What else is interesting about the number 2011?

What’s going on here?

Welcome to the new version of

Most of the site was upgraded during the weekend of the 5th-6th of March, but there is still some work to do. I think everything is now working – I had to fix a lot of things that didn’t work at first.

The Learning Zone is still awaiting content (I spent so long breaking and fixing the other sections that I ran out of time for uploading!) Please bear with me – it will start to appear in the next few days.

If you find something that isn’t working, please let me know – just leave a comment or send me an email.


What happened to the old site?

Snow days

Copies of work will also be posted on this site. To see it, just click the link for your class:
