Variation

Object of the game:

To use deductive logic to determine which variables your partner has selected.

Definition: Beginning with some statements, called 'premises', that are assumed to be true, you then determine what else would have to be true if the premises are true.Deductive reasoning is the process of reaching a conclusion that follows if the evidence provided is true and the reasoning used to reach the conclusion is correct. The conclusion must be based only on the evidence previously provided.

Set-up:

Stick a 3”x3”adhesive note on the box marked “secrecy screen”.

Procedure:

  • Player One selects any four of the six variables and writes their initial consonants in the squares under the secrecy screen. Do not use any variable more than once.
  • The Player Two writes any four of the variables in the boxes on the line marked Round 1. This is called a premise.
  • Player One gives player 2 feedback by scoring Player Two’s premise according to the following guidelines:

Count how many variables are correct and in the right column and put that number in the ‘Right Variable, Right Place’ column.

Count how many variables are correct but in the wrong column and put that number in the ‘Right Variable, Wrong Place’ column.

Write the number of wrong variables in the Wrong Variable column.

The sum of the three numbers should total 4.

  • Player Two then enters a second premise on line 2.
  • Player One scores the second premise.
  • Play continues until Player Two all 4 variables correct and in the right column, or until round 20, whichever comes first.

Players then switch roles and repeat the game.

Questions to consider:

?How can you arrive at the correct variables in fewer premises?

?When you get the correct variables in only a few rounds, how much of that is due to skill and how much to luck?

?In what ways is this game similar to processes used in scientific inquiry?
