Maths SL Assessment objectives1 Knowledge and understandingRecall, select and use their knowledge of mathematical facts, concepts and techniques in a variety of familiar and unfamiliar contexts.2 Problem-solvingRecall, select and use their knowledge of mathematical skills, results and models in both real and abstract contexts to solve problems.3 Communication and interpretationTransform common realistic contexts into mathematics; comment on the context; sketch or draw mathematical diagrams, graphs or constructions both on paper and using technology; record methods, solutions and conclusions using standardized notation.4 TechnologyUse technology, accurately, appropriately and efficiently both to explore new ideas and to solve problems.5 ReasoningConstruct mathematical arguments through use of precise statements, logical deduction and inference, and by the manipulation of mathematical expressions.6 Inquiry approachesInvestigate unfamiliar situations, both abstract and real-world, involving organizing and analysing information, making conjectures, drawing conclusions and testing their validity.Assessment OutlineAssessment componentWeightingExternalPaper 1 No calculator allowed.

This is a piece of written work that involves investigating an area of mathematics. 20%Paper 1Duration: 1 hour 30 minutesWeighting: 40%?This paper consists of section A, short-response questions, and section B, extended-response questions.?Students are not permitted access to any calculator on this paper.Question type?Questions require extended responses involving sustained reasoning.?Individual questions will develop a single theme.?Questions may be presented in the form of words, symbols, diagrams or tables, or combinations of these.?Normally, each question reflects an incline of difficulty, from relatively easy tasks at the start of a question to relatively difficult tasks at the end of a question. The emphasis is on problem-solving.Example exam questions.Maths SL Paper 1Full marks are not necessarily awarded for a correct answer with no working. Answers must be supported by working and/or explanations. Where an answer is incorrect, some marks may be given for a correct method, provided this is shown by written working. You are therefore advised to show all working.1There are nine books on a shelf. For each book, x is the number of pages, and y is theselling price in pounds (?). Let r be the correlation coefficient.Write down the possible minimum and maximum values of r (2)(b) Given that r = 0.95 , which of the following diagrams best represents the data.(c)For the data in diagram D, which two of the following expressions describethe correlation between x and y?perfect, zero, linear, strong positive, strong negative,weak positive, weak negative (2)2 The y-intercept is at (0,1) , there is a minimum point at A ( p , q) and a maximumpoint at B.Find f` (x). (2)(b) Hence(i) show that q = -2 :(ii) verify that A is a minimum point. (10)(c)Find the maximum value of f (x). (3)The function f (x) can be written in the form r cos (x - a) .(d) Write down the value of r and of a. (2)Paper 2Duration: 1 hour 30 minutesWeighting: 40%This paper consists of section A, short-response questions, and section B, extended-response questions. A GDC is required for this paper, but not every question will necessarily require its use.Example exam questions.Maths SL Paper 2Full marks are not necessarily awarded for a correct answer with no working. Answers must be supported by working and/or explanations. In particular, solutions found from a graphic display calculator should supported by suitable working e.g. if graphs are used to find a solution, you should sketch these as part of your answer. Where an answer is incorrect, some marks may be given for a correct method, provided this is shown by written working. You are therefore advised to show all working.Section A Section BCommand terms with mand TermDefinitionCalculateObtain a numerical answer showing the relevant stages in the mentGive a judgment based on a given statement or result of a pareGive an account of the similarities between two (or more) items or situations, referring to both (all) of them pare and contrastGive an account of the similarities and differences between two (or more) items or situations, referring to both (all) of them throughout.ConstructDisplay information in a diagrammatic or logical form.ContrastGive an account of the differences between two (or more) items or situations, referring to both (all) of them throughout.DeduceReach a conclusion from the information given.DemonstrateMake clear by reasoning or evidence, illustrating with examples or practical application.DescribeGive a detailed account.DetermineObtain the only possible answer.DifferentiateObtain the derivative of a function.Distinguish Make clear the differences between two or more concepts or items.DrawRepresent by means of a labelled, accurate diagram or graph, using a pencil. A ruler (straight edge) should be used for straight lines. Diagrams should be drawn to scale. Graphs should have points correctly plotted (if appropriate) and joined in a straight line or smooth curve.EstimateObtain an approximate value.ExplainGive a detailed account, including reasons or causes.FindObtain an answer showing relevant stages in the working.HenceUse the preceding work to obtain the required result.Hence or otherwiseIt is suggested that the preceding work is used, but other methods could also receive credit.IdentifyProvide an answer from a number of possibilities.IntegrateObtain the integral of a function.InterpretUse knowledge and understanding to recognize trends and draw conclusions from given information.InvestigateObserve, study, or make a detailed and systematic examination, in order to establish facts and reach new conclusions.JustifyGive valid reasons or evidence to support an answer or conclusion.LabelAdd labels to a diagram.ListGive a sequence of brief answers with no explanation.PlotMark the position of points on a diagram.PredictGive an expected result.ShowGive the steps in a calculation or derivation.Show thatObtain the required result (possibly using information given) without the formality of proof. “Show that” questions do not generally require the use of a calculator.SketchRepresent by means of a diagram or graph (labelled as appropriate). The sketch should give a general idea of the required shape or relationship, and should include relevant features.SolveObtain the answer(s) using algebraic and/or numerical and/or graphical methods.StateGive a specific name, value or other brief answer without explanation or calculation.VerifyProvide evidence that validates the result.Write downObtain the answer(s), usually by extracting information. Little or no calculation is required. Working does not need to be shown. ................
