Mentalist Vs Mathematician Slapdown

Requirements: A coin for each student & smart board or data projector.

First ask your students to toss a coin 10 times each.

Ask each student how many heads in a row they threw.

Now ask students ‘Do you think it is possible to throw 10 heads in a row?

It can be done. Here is how you do it.

Derren Brown is a UK mentalist, magician, hypnotist and maths guru. He’s awesome. He shows audiences how a lack of understanding maths, especially probability, leads to misinterpreting the facts.

Now play this video to the students:

This is the Hey! Ho! Moment.

You write down the keyword lyrics first and riff. You don’t have to be good. 

But you must never smile. It is a rule. Rappers don’t smile. They are some of the most miserable millionaires on earth.See Eminem and 50 Cent below.

Here is an example playing with Square Roots.

eg.

Whatcha gotta know ..

Whatcha gotta know 

surds .. absurd .. surds …

√2 you do.

√3 happy

√4 Want more?

√5 Ha! Ha! Ha! Staying alive. ( A little Bee Gee Riff there.)

Chorus: Hey! Ho!

Whatcha gotta know ..

Whatcha gotta know 

surds .. absurd .. surds …

√6 clickety clicks.

√7 Go to heaven.

√8 Don’t be late.

√9 Divine.

Chorus: Hey! Ho!

The trick is to get the kids to stand together and swing their hands up in the air and across chanting HEY! HO! for the chorus.

If you want to see rapping it is done Google: True Live. Keep Myself Awake

Some kid may take pity on you and do the Keyword Rap with beat box sound effects for you.
