Key Knowledge that students should know at the end of 'Topic' | This is the knowledge that students will meet for the first time in this topic | The language of chance is discussed in the context of a variety of events. Chance is then connected to probability, a numerical representation of chance from 0 and 1. The terms ‘event’ and ‘outcome’ are introduced. Students calculate theoretical probability Students compare probabilities using a variety of representations including bar models, number lines, decimals and equivalent fractions. Complementary events are introduced. The terminology ‘not A’ is introduced. Sample spaces are introduced as a tool for listing the combined outcomes of a pair of events. why multiplying probabilities of events gives the probability of the events happening together (the combined event Probability tree diagrams are introduced, using frequency tree diagrams to calculate probabilities and solve problems, Students analyse two-way tables to calculate probabilities Students meet experimental probability Students compare expected outcomes to actual outcomes | |
This is knowledge that students may have met before but will need to deepen their understanding | Students revisit methods of adding and multiplying fractions and decimals and conversion between Fractions, decimals and percentages. Two way tables | ||
