Living Maths Olympiad 2012

This is a notice from Living maths ( ) FYI

Dear Maths Colleagues,

I am very pleased to announce that the Olympiad papers/notices/resources etc. are available for download!

We have decided to move away from making a CD this year and we are allowing schools to download all the content.  The Olympiad caters for ALL learner abilities from grade R up to grade 9. Last year we had about 160 000 South African participants and about 7000 international participants.  This year we hope to have many more.

You will find a folder with notices for South African notices - these notices tell you about the event and there is also a set of instructions on how to run a hassle-free event.

The Olympiad materials have been placed in a dropbox folder.  Please feel free to forward this link to any teacher/colleague or organisation that would encourage learners to think!

You are most welcome to email me if you have any problems with the downloading of the files.

The South African leg of the Olympiad ends on 21 November.  We will collate the results within 3 days and send out certificates and Truly Calculators to all the National Prize Winners.

Good Luck and Enjoy!

What Makes 100%?

What Makes 100%?

What does it mean to give 
MORE than 100%?

Ever wonder about those people who say they are giving more than 100%? We have all been to those meetings where someone wants you to give over 100%.

How about achieving 103%?

Here's a little mathematical formula that might help you answer these questions:


Is represented as:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26.


8+1+18+4+23+15+18+11 = 



11+14+15+23+12+5+4+7+5 = 

But ,


1+20+20+9+20+21+4+5 = 



2+21+12+12+19+8+9+20 = 

AND, look how far 
ass kissing will take you. 


1+19+19+11+9+19+19+9+14+7 = 

So, one can conclude with mathematical certainty, that while 
Hard work and Knowledge will get you close, and Attitudewill get you there.
Its the
 Bullshit and Ass Kissing that will put you over the top. 
Now you know why some people are where they are!

Equal Education urgently seeking part-time Maths and English teachers

Equal Education (EE) is a social movement campaigning for quality and equal education in South Africa. Our head office is based in Khayelitsha.


EE runs a post-matric programme for 20 of its members, known as the Community Leadership Programme. The programme combines academic tutoring with political leadership and training. The aim of the programme is to build a cohesive group of young activists committed to the ideals and work of Equal Education, and to their place in it, and equipped with the academic capability needed to progress individually and collectively. At the end of the academic year, participants re-write a number of their subjects.


We are urgently seeking motivated and dedicated individuals to teach Mathematics (Maths and Maths Lit) and English (Home Language and First Additional). The positions are part-time and remunerated. Classes run in the mornings from 8h30 to 13h00. The academic component of the programme is based at 6 Spin Street, Cape Town


In addition to the minimum contact time required for each subject (plus-minus 4-5 hours a week), teachers are expected to submit teaching plans (in line with curriculum and WCED requirements), and set and grade tests, exams and assignments. Given that participants submit new School Based Assessment (SBA) marks, teachers will also need to ensure that portfolios and mark sheets are compiled for the purposes of external moderation. Applicants should preferably have 2-3 years teaching experience. Retired teachers are encouraged to apply.


Please send cover letter, CV and contactable references to Gina Fourie (
