This unit teaches students to conduct repeated chance experiments using digital tools, compare expected and actual results and understand how increasing the number of trials affects variation. Students will also describe probabilities using fractions, decimals and percentages, recognising the probability scale from 0 to 1 or 0% to 100%. The unit includes engaging activities, worksheets, games, and digital simulations to solidify understanding.
Recognise that probabilities lie on numerical scales of 0 – 1 or 0% – 100% and use estimation to assign probabilities that events occur in a given context, using common fractions, percentages and decimals
Conduct repeated chance experiments to observe relationships between outcomes; identify and describe the variation in results
Conduct repeated chance experiments and run simulations with an increasing number of trials using digital tools; compare observations with expected results and discuss the effect on variation of increasing the number of trials
Describe probabilities using fractions, decimals and percentages
Conduct Probability (Chance) experiments with both small and large numbers of trials using appropriate digital technologies
Compare observed frequencies across experiments with expected frequencies
