Identify outcomes of familiar events involving chance and describe them using everyday language such as ‘will happen’, ‘won’t happen’ or ‘might happen’
Identify practical activities and everyday events that involve chance.
Describe outcomes as ‘likely’ or ‘unlikely’ and identify some events as ‘certain’ or ‘impossible’
Conduct chance experiments, identify and describe possible outcomes and recognise variation in results
Describe possible everyday events and order their chances of occurring
Identify everyday events where one cannot happen if the other happens
Identify events where the chance of one will not be affected by the occurrence of the other
List outcomes of chance experiments involving equally likely outcomes and represent probabilities of those outcomes using fractions
Recognise that probabilities range from 0 to 1
Describe probabilities using fractions, decimals and percentages
Conduct chance experiments with both small and large numbers of trials using appropriate digital technologies
Compare observed frequencies across experiments with expected frequencies
Construct sample spaces for singlestep experiments with equally likely outcomes
Assign probabilities to the outcomes of events and determine probabilities for events
Identify complementary events and use the sum of probabilities to solve problems
Describe events using language of ‘at least’, exclusive ‘or’ (A or B but not both), inclusive ‘or’ (A or B or both) and ‘and’. Represent events in two-way tables and Venn diagrams and solve related problems
List all outcomes for two-step chance experiments, both with and without replacement using tree diagrams or arrays.
Assign probabilities to outcomes and determine probabilities for events
Calculate relative frequencies from given or collected data to estimate probabilities of events involving ‘and’ or ‘or’
Investigate reports of surveys in digital media and elsewhere for information on how data were obtained to estimate population means and medians
Describe the results of two- and threestep chance experiments, both with and without replacements, assign probabilities to outcomes and determine probabilities of events.
Investigate the concept of independence Use the language of ‘if ….then, ‘given’, ‘of’, ‘knowing that’ to investigate conditional statements and identify common mistakes in interpreting such language
Investigate reports of studies in digital media and elsewhere for information on their planning and implementation
