Mental Percentages of Amounts

  Description/Aim  

If you divide a US dollar, Australian dollar, New Zealand dollar, Euro, UK pound or any money you like (almost?) by 10 how much money have you got? Well that's 10%!

If you divide it by 1%, how much do you have?

This is easy, it's not even maths, its money! So let's stop pretending percentages are hard. Eyeball your opponent and may the best brain get the biggest buck (and that includes against your parents!).

Students Notes - Why? How? What?

Why we like this activity....
It's pure good fun. It gets you feeling sharp and looking good, and furthermore, you'll even start to believe (because
it may actually be true) that a calculator is only going to slow you down.

How this activity can be used....
It's a series of games. The aim of the game is to win and win big . . it could be you!

What to expect when using this activity, from our experience...
To be surprised at how good you are at mental maths, at how much you know without sometimes even realising you
know it, and to hone your skills so that you're ready to take on some adult competition!
