Using Tools to Experience Concepts

The world is not always laid out in neat straight lines to make it easy for us to
use our measuring tools. So what do we do when we encounter curves and still
want to find distance? 

 

We can start by approaching the situation as a game.
Using centimeters can be a lot of fun when you roll dice to determine
lengths that must be drawn along a race course!


Notice that we can only move from point to point in a straight line.
How can you turn the corner if the line is too long?

The end of the game shows that the chance rolling of the dice has
determined which player finished first - plus - both players have a very good
measured approximation of the total course length.
