Year 7 Autumn 2 2. Interpreting Data and Probability Prior Knowledge: All students will have met bar charts at primary school, though are not always familiar with analysing these in detail and in context. All students will also be familiar with the basic vocabulary of probability. Lesson Number and Title 1 Interpreting Data Learning Outcomes - - - TBAT read and get information from data shown in graphs and diagrams, including pie charts Discuss, in context, what a graph or diagram is showing Analyse and draw conclusions from graphs in a real life context Outcomes for students: Use diagrams such as pie charts, bar charts etc. to answer questions e.g. Are there more 3 children or 1 child families? Explain what a graph or diagram is showing for example, that around half the families had 2 children Comment on the relationships displayed in graphs and charts e.g. how many chairs should be put out for families at consultation evening?

What all should know Extracting and interpreting data in tables, graphs, charts and diagrams (eg. line graphs, frequency tables and What most should know Interpret diagrams and graphs (including pie charts), and draw conclusions based on the shape of 1 What some should know bar charts). Use vocabulary and ideas of probability, drawing on experience. Reason mathematically graphs and simple statistics for a single distribution. Understand and use the probability scale from 0 to 1 Find and justify probabilities based on equally likely outcomes in simple contexts Identify all the possible mutually exclusive outcomes of a single event. Solve problems Know that if the probability of an event occurring is p, then the probability of it not occurring is 1 – p; Find and record all possible mutually exclusive outcomes for two successive events in a systematic way, using diagrams and tables.
