# GRADE 9 / YEAR 10 MATHEMATICS COURSE SYLLABUS 2020-2021

# Course Outline

**Overview**

The Math Syllabus at GEMS Wesgreen International Secondary School aims to support students in building competency, confidence and fluency in their use of techniques and mathematical understanding. Throughout the year we recover and extend objectives as the focus is to develop in students their reasoning, problem-solving and analytical skills from a variety of abstract and real-life contexts.

**Learning Outcomes**

The aims of all subjects state what a teacher may expect to teach and what a student may expect to experience and learn. These aims suggest how the student may be changed by the learning experience.

The aims of the Math Syllabus are to encourage and enable students to:

- become fluent in the fundamentals of mathematics, including through varied and frequent practice with increasingly complex problems over time, so that pupils develop conceptual understanding and the ability to recall and apply knowledge rapidly and accurately.
- reason mathematically by following a line of enquiry, conjecturing relationships and generalisations, and developing an argument, justification or proof using mathematical language
- can solve problems by applying their mathematics to a variety of routine and non-routine problems with increasing sophistication, including breaking down problems into a series of simpler steps and persevering in seeking solutions.

- Calculate with values in standard form.
- Use a calculator efficiently.
- Apply appropriate checks of accuracy.
- Demonstrate an understanding of ratio and proportion.
- To include numerical problems involving direct and inverse proportion. Use ratio and scales in practical situations. Formulae for other rates will be given in the question e.g. pressure and density.

- Knowledge of compound interest formula is required.
- Calculate a given percentage of a quantity.
- Express one quantity as a percentage of another.

- Calculate times in terms of the 24-hour and 12-hour clock.
- Read clocks, dials and timetables.
- Calculate average speed.
- Use common measures of rate.

**Unit 2 –Algebra 1 - Chapter 2**

**Approximate length: 4-5 weeks**

**Syllabus - Cambridge IGCSE® Mathematics 0580 and Complete Mathematics for Cambridge IGCSE 5Th Edition-EXTENDED- David Rayner**

In this unit the children will build on their understanding of Directed numbers, Formulae, Brackets and simplifying , Solving linear equations, simultaneous equations (linear and quadratic) , quadratic equations and factorizing.

Specific National Curriculum Objectives Covered:

Blending Learning

Throughout this year there will be blended learning and we are using multiple teaching methods in order to help our students learn more effectively. All students whether face to face or learning from home will have the opportunity access all the lessons and resources. Students will use Phoenix, Teams, myimaths and GCSE Pod. Each lesson begins with a set of clearly stated objectives and an explanation of its place in the overall IGCSE syllabus. Effective learning is encouraged through frequent activities and self-assessment questions.

Links for solving past papers and links related to concepts covered to reinforce classroom learning followed will be available to students. Students will have access to worksheets with progression of difficulty, online assessments, tasks/open ended questions and fun activities through online platforms.

## Assessment

**Formative:**

Throughout the units, the children will complete graded work, quizzes and problem- solving activities which allows the teacher to assess the students’ attainment and inform their planning.

For each unit the students complete written quizzes, online quizzes as well as Chapter- wise tests (Topic Tests). Quizzes are taken based on 1-chapter assessment, where Tests are combined as per the requirement i.e. 2 to 3 chapters/topics – sections. This allows us to see progress across the units and align our planning.

**Summative:**

At the end of each term we complete internal and standardized tests. This allows us to measure the students’ progress throughout the term and year. End of term 1 they have IGCSE format combined exam for both papers and two separate exams for P-2 and P-4 for End of Year Exam. This is practice / preparation for their final IGCSE examinations. At the end of the 2 year course, students appear for their final IGCSE examination for Syllabus - Cambridge IGCSE® Mathematics 0580.
