Estimation Frustration

Game: Estimation Frustration 

Equipment: 2 dice, 1 calculator

How to Win: The Winner is the first person to 40 points

How to Play: Roll the dice for your partner. Make a two-digit number (ext/ena is number of digits/decimals etc). E.g. roll a 4 and 3 could make 3.4, 4.3, 34, 43 etc.
Write this number down.

Roll the dice again and make a second number. Write this number down. 

Show these two numbers to your partner. They have 10 seconds to write an estimate of the product.

Use a calculator to work out the answer and compare to the partners estimate.

Score as follows:
Spot on = 20 pts
Less than 10/100/1000 off = 10 pts
Between 10/20, 100/200, 1000/2000 off = 5 pts
More than this = 0 pts
