The markers will follow the mark schemes in this booklet, which is supplied to teachers for information. This booklet contains the mark schemes for the levels 3–5 tests A, B and mental mathematics. Level threshold tables will be available on the QCA website on 21 June 2004 (www.qca.org.uk/). General guidance The structure of the mark schemes The marking information for each question is set out in the form of tables, which start on page 6 of this booklet. The ‘question’ column on the left-hand side of each table provides a quick reference to the question number and the question part. The ‘mark’ column indicates the total number of marks available for each question part. On some occasions, the symbol U1 or U2 may be shown in the mark column. The ‘U’ indicates that there is a ‘Using and Applying Mathematics’ element in the question. The number, 1 or 2, shows the number of marks attributed to using and applying mathematics in the question. The ‘requirement’ column may include two types of information: a statement of the requirements for the award of each mark, with an indication of whether credit can be given for correct working; examples of some different types of correct response. The ‘additional guidance’ column indicates alternative acceptable responses, and provides details of specific types of response which are unacceptable. Other guidance, such as the range of acceptable answers, is provided as necessary. Additionally, for the mental mathematics test, general guidance on marking is given on page 16, together with a ‘quick reference’ mark scheme. Applying the mark schemes In order to ensure consistency of marking, the most frequent procedural queries are listed on pages 2 and 3 with the action the marker will take. This is followed by further guidance on pages 4 and 5 relating to the marking of questions that involve money, time and other measures. Unless otherwise specified in the mark scheme, markers will apply the following guidelines in all cases. Sourced from SATs-Papers.co.uk http://www.SATs-Papers.co.uk 1 What if ...? Marking procedure The child’s response is numerically or algebraically equivalent to the answer in the mark scheme. Markers will award the mark unless the mark scheme states otherwise. The child’s response does not match closely any of the examples given. Markers will use their judgement in deciding whether the response corresponds with the statement of the requirements given in the ‘requirement’ column. Reference will also be made to the additional guidance and, if there is still uncertainty, markers will contact the supervising marker. The child has responded in a non-standard way. Calculations, formulae and written responses do not have to be set out in any particular format. Children may provide evidence in any form as long as its meaning can be understood. Diagrams, symbols or words are acceptable for explanations or for indicating a response. Any correct method of setting out working, however idiosyncratic, will be accepted. There appears to be a misreading affecting the working. This is when the child misreads the information given in the question and uses different information without altering the original intention or difficulty level of the question. For each misread that occurs, one mark only will be deducted. In one-mark questions – 0 marks are awarded. In two-mark questions that have a method mark – 1 mark will be awarded if the correct method is correctly implemented with the misread number(s). No answer is given in the expected place, but the correct answer is given elsewhere. Where a child has shown understanding of the question, the mark(s) will be given. In particular, where a word or number response is expected, a child may meet the requirement by annotating a graph or labelling a diagram elsewhere in the question. The response in the answer box is wrong, but the correct answer is shown in the working. Where appropriate, detailed guidance will be given in the mark scheme, which markers will follow. If no guidance is given, markers will examine each case to decide whether: the incorrect answer is due to a transcription error; the child has continued to give redundant extra working which does not contradict work already done; If so, the mark will be awarded. the child has continued to give redundant extra working which does contradict work already done. 2 If so, the mark will be awarded. If so, the mark will not be awarded. Sourced from SATs-Papers.co.uk http://www.SATs-Papers.co.uk What if ...? Marking procedure The child’s answer is correct but the wrong working is shown. A correct response will always be marked as correct. The correct response has been crossed out and not replaced. Any legible crossed-out work that has not been replaced will be marked according to the mark scheme. If the work is replaced, then crossed-out work will not be considered. More than one answer is given. If all answers are correct (or a range of answers is given, all of which are correct), the mark will be awarded unless prohibited by the mark scheme. If both correct and incorrect responses are given, no mark will be awarded. The answer is correct but, in a later part of the question, the child has contradicted this response. A mark given for one part will not be disallowed for working or answers given in a different part, unless the mark scheme specifically states otherwise. Recording marks awarded on the test paper In the shaded margin there is a mark box for each question part. For the written tests, the number of marks gained on each double page will be written in the total box at the bottom of the right-hand page. For all the tests, the total number of marks gained on each paper will be recorded on the front of the test paper, and on the mark sheet. All questions in the tests, even those not attempted by the child, will be marked with a ‘1’ or ‘0’ entered in the mark box. A two-mark question which is correct has ‘1’ entered in both mark boxes. A two-mark question which is incorrect, but which has sufficient evidence of working or method as required by the mark scheme, will have ‘1’ entered in the first mark box and ‘0’ in the second. Otherwise ‘0’ will be entered in both mark boxes. Test A carries a total of 40 marks. Test B also carries a total of 40 marks. The mental mathematics test carries a total of 20 marks. The 2004 key stage 2 mathematics tests and mark schemes were developed by the Mathematics Test Development Team at QCA.

Ignore any annotation, even if in the answer space, and mark only the answer. Accept an unambiguous answer written in the stimulus box, or elsewhere on the page. Full mark scheme information is given on page 18. In addition, a ‘quick reference’ mark scheme is provided on page 17. This is presented in a similar format to the children’s answer sheet. General guidance The general guidance for marking the written tests also applies to marking the mental mathematics test. In addition, the following principles apply. 1. Unless stated otherwise in the mark scheme, accept answers written in words, or a combination of words and figures. 2. Where units are specified, they are given on the answer sheet. Children are not penalised for writing in the units again. 3. Where answers are required to be ringed, do not accept if more than one answer is ringed, unless it is clear which is the child’s intended answer. Accept also any other way of indicating the correct answer, eg underlining. 16 Sourced from SATs-Papers.co.uk http://www.SATs-Papers.co.uk Mental mathematics 2004 quick reference mark scheme Practice question 11 Time: 5 seconds 48 hours 1 1 4 Accept 0.25 or equivalent fractions 38 2 12 4500 m 13 –14 °C 210 3 Do not accept 14 – 6 4 14 5.2 15 0.075 44 5 Time: 10 seconds Time: 15 seconds 99 6 16 7 890 17 55 Bus times 07:15 07:35 07:55 08:15 18 1 100 9 £1.65 10 260 340 minutes 19 1 20 140 300 20 8 100 2 3 3 4 40 5 10 220 cm2 20 Accept 165p Sourced from SATs-Papers.co.uk 60 degrees http://www.SATs-Papers.co.uk 17 Mental mathematics questions 1–20 Question Requirement Mark 1 48 hours 1m 2 38 1m 3 210 1m 4 6 1m 5 44 1m 6 99 1m 7 20 minutes Additional guidance 1m 8 1 20 1 100 2 3 3 4 5 10 1m Accept any other way of indicating the answer, eg underlining.
