Functional Question And lesson Foundation (Statistics 9) For the week beginning ….
Assessment Objective - AO3 Developing AO3 skills is a process that depends on giving learners confidence to: · Try different approaches · Make mistakes and rectify them in a constructive environment · Justify decisions and explain consequences · Express ideas and communicate conclusions in a variety of ways and to different audiences. AO3 seeks to assess a learner’s ability to: · Process information · Pose problems and pursue them · Conjecture and investigate within mathematics · Reason concisely · Evaluate and check methods and results · Present solution(s) effectively There is a link to the three strands in Functional Mathematics: · Represent (strategy) · Analyse · Interpret However, not all AO3 questions will be “functional”.

This bar chart represents the scores that were obtained when a number of people entered a penalty-taking competition. Each person was allowed six penalty kicks. How many people entered the competition? How can you tell?
Can you think of another statistical diagram that could have been used to represent this data?
Does the pie chart tell you how many people entered the competition?
Can you find the mode from the pie chart? Yes or No?
Can you find the mean from the pie chart? Yes or No?
Can you estimate the percentage that scored one goals?
If only four people had scored six goals, what would the pie chart have looked like?
If I halve/double the heights of all the bars in the bar chart, what will happen to the pie chart?
Today’s Task Work together to match the cards from each set. Try to do this without doing calculations. Take turns at explaining how you know particular cards match. Things to think about... By looking at the bar chart can you see which section of the pie chart should be biggest or smallest? Are any of the sections of the pie chart going to be the same size?
Plenary Which cards were the easiest to match up and why? Which cards were the hardest to match up and why?
