# Course Outline

## Overview

The Math Syllabus at GEMS Wesgreen International Secondary School aims to support students to develop their ability to calculate fluently, to reason and solve problems through application of knowledge and transferable skills. Throughout the year we recover and extend objectives as the focus is on securing an understanding in the subject by developing a greater depth.

## 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 generalizations, 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.

Specific CIE Objectives Covered:

• understand the gradient of a curve at a point as the limit of the gradients of a suitable sequence of chords, and use the notations
• Only an informal understanding of the idea of a limit is expected. e.g. includes consideration of the gradient of the chord joining the points with x coordinates 2 and (2 + h) on the curve y = x3. Formal use of the general method of differentiation from first principles.

Unit 5 – Further differentiation

Approximate length: 1 week

In this unit the children will build on their understanding of using differentiation, tangents and normal, maximum and minimum points, increasing and decreasing functions, point of inflection, the second derivative, applications and the chain rule.

Specific CIE Objectives Covered:

• Use the derivative of xn (for any rational n), together with constant multiples, sums and differences of functions, and of composite functions using the chain rule.
• Apply differentiation to gradients, tangents and normal, increasing and decreasing functions and rates of change.
• Locate stationary points and determine their nature, and use information about stationary points in sketching graphs.Unit 6 – Integration Approximate length: 2 weeksUnit 6 – Integration Approximate length: 2 weeks

Unit 6 – Integration Approximate length: 2 weeks

In this unit the children will build on their understanding of reversing differentiation, finding area under a curve, area as the limit of a sum, area below the x-axis, the area between two curves, the area between a curve and the y-axis, the reverse chain rule, improper integrals, finding volumes by integration.

Specific CIE Objectives Covered:

• Understand integration as the reverse process of differentiation, and integrate (ax + b)n (for any rational n except –1), together with constant multiples, sums and differences.
• Solve problems involving the evaluation of a constant of integration.
• evaluate definite integral
• Use definite integration to find – the area of a region bounded by a curve and lines parallel to the axes, or between a curve and a line or between two curves – a volume of revolution about one of the axes.

## Blended 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 to access all the lessons and resources. Students will use Phoenix and myimaths. Each lesson begins with a set of clearly stated objectives and an explanation of its place in the overall CIE AS/A level 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 2 they have CIE format exam for P1. This is practice / preparation for their final CIE examinations. At the end of one year course, students appear for their final CIE examination for Syllabus - Cambridge CIE® Mathematics 9709.
