Birthday Clues

When Was Will Born?


A prime number has two and only two factors.

Consecutive numbers are next to each other in the sequence of counting numbers


Thirty days hath September,
April June and November.
All the rest have thirty-one
Excepting February alone,
Which has twenty-eight days clear,
But twenty-nine each Leap Year.


The number 22222 is given in base 5. It means:

2 x 625 +
2 x 125 +
2 x 25 +
2 x 5 +
2 x 1


The day is a two digit prime number. The two digits are consecutive numbers.


The number of days in the month is a multiple of the number of letters in the month's name.


The year was a leap year which began on a Saturday.
It is 222225 + 2.

How old would he be if he was alive today?

  • EK, Dorset
  • Wonderful! I have top set year 5 and they found it fun. Interesting to see how much they knew about Shakespeare too!
  • Mr Heeley's y7, Rawthorpe High, Huddersfield
  • Gosh, he would be even older than Mr Heeley!
    'So shaken as we are, so wan with care, for find we a time for frightened peace to pant, and breathe short-winded accents of new broils, to be echoed in lands afar remote' Opening line to Henry IV part 1.
    See, Maths teachers can be quite literate too!!!

    Have a lovely summer Transum xx
  • Carole, 6A Cragieburn PS Australia
  • My Grade 6 Class really enjoyed working out this problem. We worked out that Will would be 448 years old if he was still alive today! Mrs Pyne and 6A.
  • Class 1.6, Brechin High, Scotland
  • We definitely needed the clue for the year. However, it was very challenging and worthwhile! Thank you. Class 1.6.

Have you read Craig's book yet?

Craig Barton must surely be the voice of Mathematics teachers in the UK. His wonderful podcasts interviewing the industry experts have culminated in this wonderful book. As Craig says: "I genuinely believe I have never taught mathematics better, and my students have never learned more. I just wish I had known all of this twelve years ago..." more...

"How I wish I'd taught Maths" is an extraordinary and important book. Part guide to research, part memoir, part survival handbook, it’s a wonderfully accessible guide to the latest research on teaching mathematics, presented in a disarmingly honest and readable way. I know of no other book that presents as much usable research evidence on the dos and don’ts of mathematics teaching in such a clear and practical way. No matter how long you have been doing it, if you teach mathematics—from primary school to university—this book is for you." Dylan Wiliam, Emeritus Professor of Educational Assessment, UCL.

Casio Classwiz Calculator

There is currently a lot of talk about this new calculator being the best in its price range for use in the Maths classroom. The new ClassWiz features a high-resolution display making it easier to view numerical formulas and symbols but it isn't a graphical calculator as such (it has the capacity to draw graphs on your smart phone or tablet, via a scannable QR code and an app).

As well as basic spreadsheet mode and an equation solving feature you also get the ability to solve quadratic, cubic or quartic polynomial inequalities and the answer is given just as it should be written down, using the correct inequality symbols!

This calculator has a high-performance processor and twice the memory of previous models ensuring speedy operation and superior computational power.more...

Student Activity


July 14th is Transum's birthday!


The Same Birthday

It would be fun for everyone in the class to stand in a line in order of their birthdays. Does anyone have the same birthday as someone else?

Alice in Wonderland learns that in a class of 23 pupils the probability that two have the same birthday is more than a half. Alice is a fictional character created by author and mathemetician Lewis Carroll (1832-1898) but the probability fact is true.

Find more interesting facts like that on the Mathematics Trivia page.
