What are the chances?

We have been working on the Statistics and Probability section of the Maths curriculum in our Monday maths time. The curriculum statements for Grade 5 and 6 are in the images below.

Probability is the measure of how likely an event is.

We have sorted probability words, looked at a scale of probability and worked on collecting data about the chances of rolling numbers on a fair die. One of things that we discussed was how the results of our experiments could vary from the theoretical probability.

Die Challenge

We rolled a die and recorded our results for 12 rolls and each result was very different.

We then combined our results using a Google form and could see that the more results we gathered the closer these results came to the theoretical probability outcome of an equal 1 in 6 chance of rolling each number.

We would love to collect more data and ask that you have a go. Roll a fair die 12 times and record your results on our Google form. The graph should change over time as more results are recorded.

We have also written a list on our books in response to an open ended question that Mrs S put on the board.

Listing Outcomes

We needed to think about outcomes that have a 1 in 2 chance and give as many examples as we could. The outcomes we were thinking about were those in the middle of our probability scale as a 1 in 2 chance can also be described as 0.5 or 50% or 1/2. The outcomes are equally likely to occur.

What ideas could you add to our list? Please leave a comment sharing your thoughts.
