Estimation. School walls - don't tell Pink Floyd!

Estimation. How many bricks?

 Pink Floyd

This is  really simple lesson on estimation that makes the topic REAL!

It is easy to do and works, plus it allows you to escape the confines of the classroom.

I guess we have all heard the song 'The wall' by Pink Floyd. I enjoyed listening to it but was never quite sure about the lyrics. 

At this time of year I think most teachers would prefer to listen to Alice Cooper, you know the song 'Schools Out'. Just to remind you about Pink Floyd’s lyric

'We don't need no education
We don't need no thought control
All in all it’s just another brick in the wall'

Negative into positive with a paper aeroplane

Inferior models

Irritated by paper aeroplanes being thrown in your classroom? It happens to all of us during out teaching career at one time or another, some ‘character’, usually a boy, has learnt how to make a paper aeroplane and uses your class to demonstrate his new found skill. I am always amazed at the poor level of construction of these missiles; they are usually just successive folds along a central axis, a demonstration of symmetry. My dad taught me a far more intricate and aesthetically pleasing method but I’m not sure if it flew as far as the, in my opinion, inferior models.
