Functional Skills Mathematics: implications for teaching and learning
Mathematics: Introduction • The papers were divided into three tasks: tennis, offices and coffee shop • Contexts were chosen to reflect the everyday use of mathematics • Some questions were common to both Level 1 and Level 2 assessments • The total mark for each paper was 60
Mathematics: Introduction • Tasks required students to apply knowledge • Many tasks required students to choose the method of solution and the operations needed to solve the problem • In some tasks students were required to choose or interpret the data to use to solve the problem • Students were expected to express their answers accurately
What students could do well: Level 1 Students were generally successful at: • interpreting data from simple tables and graphs • drawing scaled diagrams • writing a series of numbers in order • drawing lines of symmetry on simple geometric shapes • measuring angles and length
What students could do well: Level 2 Students were generally successful at: • interpreting data from tables and graphs • interpreting information presented in unfamiliar ways • working with equivalent fractions and percentages • using unfamiliar mathematical formulae given in the question (see question 13)
Question Performance Statistics The facility value of a question is one way of its measuring performance • The facility value = the proportion of students who gained the marks • A facility value of 1 means that all students got the question correct • A facility value of 0.5 means that 50% of students gained the marks
Question Performance Statistics Facility values – Level 1
Question Performance Statistics Facility values – Level 2
Question Performance Statistics Common questions Q6: About half of Level 1 and Level 2 students were able to work with ratios in the context of diluting drinks.
Question Performance Statistics Common questions Q7: Less than half of Level 1 students could use data given in a simple table, work out a range and carry out a two-step calculation involving rectangular area. Almost two thirds of Level 2 students gained the marks in this question.
Question Performance Statistics Common questions Q11/Q9: About half of Level 2 students were able to convert mm to metres and work with linear dimensions. Less than a third of Level 1 students gained the marks in this multi-step question.
How centres can help students improve their performance: • Emphasise the importance of reading carefully • Encourage students to show the detailed steps • Give students opportunities to use mathematics in everyday life • Make sure students have the correct equipment for the assessment
How centres can help students improve their performance: • Emphasise the need for students to make sure they write numbers clearly • Give students practice in interpreting answers shown on a calculator • Give students practice in solving problems involving time, money, areas, ratios and large numbers
Examples of student responses In the following exemplars: Extracts from the questions appear in boxes. • text without boxes are comments or questions • intended to prompt discussions Student responses appear in boxes.
Level 1: Q2a The attendance for the first week of the 2006 Championship was 467,191. What is the number 467 191 rounded to the nearest thousand? • what are the key skills required to get the answer 467 000? • what errors have students made in the following answers? • how could you help students avoid these errors? 470 191 467 190 467 291 500 000 468 191 467 470 000
Level 1: Q10a In an office, 1/5 of the workers are male. What percentage of the workers are male? • what understanding is required to get the answer 20%? • how could you help students who gave the following • answers? 1.5% 5% 15% 25% 75%
Level 1: Q7d 30 m 12 m This is the plan of the office in Plymouth What is the total cost of the rent for this office in Plymouth for a week? (rent is £97 per m ) [2 marks] 2 This student has not followed through and so only scores one mark. 12 x 30 = 360 The correct answer is £34 920. Can you see how this student got this answer? £4074
Level 1: Q10b For how long was this person at work on Wednesday? Give your answer in hours and minutes. • What do students have to do to get the correct answer of • 7 hours 45 minutes? • What errors have students made in giving the following • answers? 8 h 45 min 8 h 15 min 7 h 15 min 6 h 45 min
Level 1: Q2a Correct answer: 467 000 How would you mark these responses? Level 1: Q10b Correct answer: 7 hours 45 minutes Do you agree with the marking of this response?
Level 1: Q4a The table shows the prize money won by the two finalists in the men’s finals of 2006 and 2007. What was the total prize money won by the two finalists in 2007? A common incorrect answer was £1 355 000. What error has been made here?
Level 2: Q13a The calculation required in this question was: £6.20 x 5.5(hrs) x 6 (days) = £204.60 A common incorrect answer was £197.16, which results from using 5.3 instead of 5.5 and illustrates an error in calculating with time values. Students also need practice in using the correct notation for money, for example common answers included: £204.60p £204.6 £20.406 £20460
Level 2: Q13b Sometimes Sally works extra hours. Mabel pays Sally £6.20 plus half as much again for each extra hour. What is Sally paid for each extra hour? The correct calculation leads to the answer £9.30. A common error was to only calculate half of £6.20. Students may have misread the question, possibly reading extra as the addition to the hourly rate.
Level 2: Q2b How do the number of aces served by male players compare with the number of aces served by female players? These answers do not gain the mark. Why not? The number of aces are bigger for female than for males. In 5 matches Krajicek had 45 aces. It doubled. Here is an example of a correct answer: Males served more than twice as many.
Marking Exercise Mark a Level 1 and a Level 2 paper.
Key points Students should: • read the question carefully • show the detailed steps to their calculations • write numbers clearly • use a calculator, ruler and protractor, where appropriate • use the correct notation for money and time
Key points Centres should: • give students practice in interpreting answers shown on a calculator • give students practice in solving problems involving time and money, areas, ratios and in working with large numbers • give students opportunities to use mathematics in everyday life via a variety of appropriate contexts
