Activity 1, Transum

Tuesday, September 8, 2015

"This is a game for two players. Two dice are rolled and their numbers multiplied together. If this product is odd, Player 1 earns a point. If this product is even Player 2 earns a point. The first player to earn 20 points wins.
This came can be varied by changing the number of dice used, changing the numbers on the dice and changing the operation from multiplication to division, addition or subtraction.
You can analyse the fairness of the game by constructing a possibility space."

Activity 2, Transum

Tuesday, September 8, 2015

"The first part of this activity requires pupils to imagine a coin being tossed 50 times. They should write down the results of their imaginary tossing as a list of Hs and Ts.
Then they sould a real coin, or one of the coins provided above to produce a list of 50 actual tosses.
Finally they should compare the two lists. What is the longest run of Hs or Ts in each list? Make a tally char of run length for the two lists and they should notice that the real toss list has slightly longer runs as our imaginations tend to want to even out the number of heads and tails more than would naturally occur."

Activity 3, Transum

"Skunk is a two dice game for the whole class to play together and contains elements of chance and choice. You can find all of the instructions on the Skunk Game page."
