http://www.nzmaths.co.nz/bright-sparks Best One - choose the number of frogs
There are lots of applets of the same puzzle - it is very popular!
http://www.subtangent.com/maths/ig-leapfrog.php Good one - you can start with two frogs
Friday - Last Period 27th April

Psychic - there is maths behind the magic!


We proved it algebraically - we let a and b represent the two digits
10a+b was the chosen number
a+b was taken off
10a + b - (a + b)
=10a + b - a - b
So the digit in the tens col, multiplied by 9 is the answer => always a multiple of 9!
We also tested 99 - which gives 81 - so 90 and 99 are multiples of 9 that can never be chosen.

Then after doing some serious work on solving equations which had algebraic fractions in them we spent a few minutes on this:
