Maths Fail

Saw these ten math(sic) fails

… and was reminded of this:

argos fail

… that I found last year.

It can be quite tricky, this maths stuff.

(Don’t worry Argos – I’ll be singing your praises in a week or so when I introduce my readers to the “Argos Game”)

The Longest Day

Pi

21st June 2013 – the Summer Solstice, the longest day.

Druids, and others, have gathered at Stonehenge to celebrate the day.

Despite driving past Stonehenge on many occasions and, many, many years ago, climbing over the stones themselves (in those days you had un-restricted access to the monument. Today, you are kept a respectful, if disappointing, distance from the stones) there’s not a lot I can tell you about Stonehenge, and I certainly have no new insight into its mystery.

But, have you noticed, the stones look like the symbol for Pi: π and they are in a circle, too?

And that’s kind of cool.

Three Reasons to Love 121

121

121 – One Hundred and Twenty One

Here’s three reasons to love this number:

  1. Its a palindromic number – the same backwards as it is forwards
  2. It’s a square number – 121 = 11 x 11 = 112
  3. It always reminds me of the mobile company 0ne2one which morphed into T-Mobile. one2one ran a great series of ads where a star explained who they would like to have a one 2 one with. They’ve always stuck with me and they always reminded me that 11 squared is one2one – 121.

Here’s one of one2one’s ads, where Kate Moss tells us how she’d like to meet Elvis:

The Apprentice

I don’t watch much TV, but the “Big Bang Theory” and “The Apprentice” are my two must see’s each week (and, as a treat, I do stay up and watch the first half of Question Time on a Thursday night. How sad is that?!)

If you haven’t yet watched this week’s Apprentice then don’t. A more cringe worthy piece of viewing I haven’t seen in a long time. I couldn’t watch, I had to scuttle off to the kitchen and make myself some toast.

This week, the future captains of industry had to put on corporate ‘away-days’ – team-building, bonding, improving communication skills – all that sort of thing. It was painful to watch – at one point one ‘exec’ asking “what was the point of that” as he finished the cup-cake decorating activity. It was an embarrassing collection of badly planned and poorly executed tasks, mixed in with a liberal dose of meaningless management speak:

“Success in work, success in yourself is just success in life”

Its easy to knock these wannabees – but what would I have done in their place? Well, whilst making  my toast, I asked myself that question and soon realised that running a corporate away day was not much different from teaching and I would use a couple of tasks I’ve used in my classroom – great for developing problem solving skills, but also for developing communication skills mainly because, at the start, everyone just shouts out their own ideas and nobody listens. But to succeed, the teams need to collaborate and listen to each (and do a little maths along the way.)

The first task I would have  used is a magic squares challenge.

Arrange nine chairs in a three by three grid. Pick nine people to take part and get them to write one of the numbers from 1 to 9 on a piece of paper and stick it onto them. (OK – if I were doing this with a bunch of ‘execs’ I’d have made some fancy numbered bibs, but for the classroom A4 paper will suffice) Get them to sit on the nine chairs in order from one to nine. Then explain that the task is to organise themselves so that each horizontal, vertical and diagonal row adds up to the same total and tell them to start. Stand back and watch! If you’ve got more  than nine (and, if your a teacher and not a corporate trainer, you’re going to have more than nine!) then set up another set of nine chairs and turn it into a competition. I often do this in September – its fascinating to watch and gives a good indication of who’s loud, who listens, who thinks, who follows.

Another task would be the ‘Frogs Investigation’ – I’m sure you all know this one: you have seven lily pads, 3 green frogs on one side, 3 brown frogs on the other side and they have to swap places. Frogs can only move by sliding onto an empty adjacent lily pad or hoping over one frog onto an empty lily pad. Use chairs for lily pads and get volunteers to be the frogs – I find it easier to pick girls to be one type of frog, boys to be the other – and set them off. Again, as well as the problem solving needed for this task, it also draws out communication skills and team work and is probably as valid and as useful in the corporate training arena as it is in the maths classroom on a gloomy February afternoon.

And there’s loads of other tasks and investigations that we ‘do’ in maths that would be perfect for developing business skills – Sir Alan, are you hiring? I’ve got a great idea for a new corporate training venture …

Gove Levels Part II – Update

(and an apology)

On Wednesday I wrote about the proposed new ‘I – Levels’ and I’m grateful to those of you that have been in touch with me to point out my error. It seems (and this would make sense) that all exams will be taken in June, with resits available only for maths and English in November, not, as I implied, that maths and English final exams would be taken in November, with all other exams being taken in June.

Sorry for any confusion! In my defence, I was summarising from several different sources, at least three of which directly quoted:

“Under the new system, all end-of-course exams will be taken in the summer, except for English and maths papers that will be sat in November.”

But herein lies the problem – no-one has been able to establish the source of the leak and so no confirmation of anything contained in Wednesday’s announcement can be verified or confirmed.

Ofqual are vehemently denying the leak, and they’ve always been water tight in the past, so its reasonable to assume that the leak didn’t come from them.

My guess – and it is only a guess – is that the leak came from somewhere in “Team Gove”, providing another opportunity to promote Michael Gove into the public’s consciousness, all part of the grand master plan to see him one day have the keys to Number 10.

So what can we take away from Wednesday’s leak? The general consensus is that the following three items are likely to be the central pillars of any new exam system:

  • Pupils will be assessed solely on exams at the end of year 11. That means no coursework, with the exception of a 10% practical element in the science subjects and no modular exams during the period of study.
  • The opportunity to take resists will be reduced. With the (possible) exception of English and maths, pupils will have to wait a year before re-sitting any exams.
  • Numerical grading system. Grades 8 to 1 will replace A* to E.

This remains, of course, speculation – Ofqual are about to embark on a period of consultation – but I hope I’ve cleared up any confusion. Sorry!
