GCSE Mathematics (1MA1) – Higher Tier Paper 2H marking scheme

GCSE Mathematics (1MA1) – Higher Tier Paper 2H marking scheme November 2020 student-friendly mark scheme Please note that this mark scheme is not the one used by examiners for making scripts. It is intended more as a guide to good practice, indicating where marks are given for correct answers. As such, it doesn’t show follow-through marks (marks that are awarded despite errors being made) or special cases. November 2020 student-friendly mark scheme Please note that this mark scheme is not the one used by examiners for making scripts. It is intended more as a guide to good practice, indicating where marks are given for correct answers. As such, it doesn’t show follow-through marks (marks that are awarded despite errors being made) or special cases. It should also be noted that for many questions, there may be alternative methods of finding correct solutions that are not shown here – they will be covered in the formal mark scheme. NOTES ON MARKING PRINCIPLES Guidance on the use of codes within this mark scheme M1 – method mark. This mark is generally given for an appropriate method in the context of the question. This mark is given for showing your working and may be awarded even if working is incorrect. P1 – process mark. This mark is generally given for setting up an appropriate process to find a solution in the context of the question. A1 – accuracy mark. This mark is generally given for a correct answer following correct working. B1 – working mark. This mark is usually given when working and the answer cannot easily be separated. C1 – communication mark. This mark is given for explaining your answer or giving a conclusion in context supported by your working. Some questions require all working to be shown; in such questions, no marks will be given for an answer with no working (even if it is a correct answer). Part Working an or answer examiner might expect to see Mark Notes (a) 2  2  3  7 M1 This mark is given for a 2, 2 3 and 7 seen A1 This mark is given for the correct answer only (b) 60, 120, 180, 240, 300, 360, 420 … M1 This mark is given for a method to find 84, 168, 252, 336, 420 … the LCM or 84 = 2  2  3  7 60 = 2 × 2 × 3 × 5 LCM = 2  2  3  5  7 420 A1 This mark is given for the correct answer only Question 2 (Total 5 marks) Part Working or answer an examiner might expect to see Mark Notes (a) M1 This mark is given for 2 and 10 correctly placed in the intersection 4 6 8 2 10 1 5 M1 This mark is given for 4, 6 and 8 placed in A only or 3 7 9 1 and 5 placed in B only or 3, 7 and 9 placed in (A  B) C1 This mark is given for all numbers correctly placed in the Venn diagram (b) n(A  B) = 2 M1 This mark is given for a method to identify the number of elements in A  B 2 A1 This mark is given for the correct answer 10 only It should also be noted that for many questions, there may be alternative methods of finding correct solutions that are not shown here – they will be covered in the formal mark scheme.
