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.
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.
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.
