Probability – using die

You will now have a go at watching and observing collected data to see if you can spot any patterns.

First you need to collect some data!

You will need two dice, a pencil, and a copy of this sheet (also below)  Rolling dice game chart

Screen Shot 2014-06-06 at 7.37.31 AMYou will be rolling the dice 20 times. You will be recording how many of each number (the total of both dice) you get using tally marks. You will do this a total of four times. The objective is to notice an patterns and trends, and see if you get better at predicting the numbers you will roll in only 20 rolls.

Make some agreements as to how you will proceed if you are working in pairs (e.g. how many rolls you will each take, who will record, etc… ). Then :-

  • In the first grey column predict how many of each number you think you will get
  • Then actually roll the dice 20 times. Record what you get using tally marks.

When you are done, see how good you were at predicting by comparing your prediction and the actual numbers you got. Try to get better in the next three times you do this. Here is the second half of the ‘Rolling dice game chart’.

  1. How easy was it to learn from the data?
  2. How good were you at predicting? Did you get any better in the 2nd, 3rd, and 4th roll? Why/why not?
  3. What were some of the problems you had while doing this activity?
  4. If you had to do this again, how would you improve it?
