Roll away from 20: group Tahi

Here we are subtracting from 20.  We have two large dice - we add the total and then subtract from 20.  Our aim is to get to zero as quick as we can. 

Finding the Difference:

This is something we all need to work on.  It can be a little tricky and it is another word for subtraction.  We are working out the difference between two measurements.  We are taking away one measurement from the other?  Please practice this at home.

The difference is over double the size.  Wow!  Are you under or over half the size of the tallest man in the world??
