10. 6 degrees of separation

July 9, 2013

You are, according to mathematicians, 1 degree of separation away from anyone you know. Then two degrees from people they know and son on.

Professor of mathematics Jason Brown explained in the Chronicle Herald, California, how the 6 degrees of separation theory works:

pic 19 holding_hands_six

 For example, suppose that you are or have been acquainted with, say, 400 people. Each of those may know 400 others, giving rise to about 400 times 400, or 160,000 people, you may know in two steps.

Again if each of those individuals knows 400 people, you would only be three steps away from about 400 times 160,000, or 64 million people, and so on.
six-degrees

This is exponential growth.

Assuming we each know 400 people.

x = total number of people involved.

n = degrees of separation

 

x = 400n

If n = 6

x = 4006

x = 4 x 1015

As the population of the earth is only 7 Billion or 7 x 109, it seems likely that we can be linked to anyone else on earth in less than 6 degrees of separation, 4 maybe.

Here is an awesome Middle School Maths PDF from PBS MATHONLINE based on Rumours.

It is an excellent introduction to exponential functions.

7 Cardboard Labyrinth

April 9, 2013

Maths-is-Awesome Activity

Cardboard Labyrinth

Skills: Graphing, modelling …. mostly generates inspiration

Levels: Any

98.1 Carlos-Teixeira-Layered-Cardboard-Labyrinth-Installation-2-537x358

Brazilian architect Carlos Teixeira created an incredible labyrinth made entirely from layered recycled cardboard for the 29th International Biennial in Sao Paulo.

More info here.

Labyrinths are mysterious. And mathspiggies, look at that lovely parabola. Making a labyrinth on this =scale may be beyond the resources of a maths class … but then again some imagination and some maths skills and voila:

98.3 thumb_4787_img-3329

In phase one of the project 240 students at Kingsford Primary School in Aberdeen used interconnecting materials to design and build a labyrinth inspired by the story of Icarus.

10 DYI Construction Set

April 8, 2013

Maths is Awesome Activity

DYI Construction Set

Skills: Geometry, measurement, symmetry, area, angles.

Year Level: Year 7

You will find more info here.

95 Happy Hooligans Construction Set

This idea is gobsmacking. We live in a consumer world so the thought of making your own construction set is foreign to us.

Building your own cardboard construction set involves:

* Lots of maths

and if

* Every pupil made 20 construction pieces now you can make something huge for a maths display. eg. giant parabola, π, √2

Or

think really BIG.
