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.

Investigating Adaptations with a focus on Birds

For our Science Inquiry with Mrs C we have just completed some work on birds and the adaptations they have developed to survive in their environments.

Each of us selected a bird and researched to find out the physical and behavioural adaptations it needed to live in the environment it could be found in around the world.

As part of the presentation of our information we created scaled 3D models of our birds. Take a look at some of our finished models.

Have you created a 3D model before? What materials did you use? Do you have any interesting facts about birds? Please leave a comment sharing your thoughts.
