GRADE 8 / YEAR 9 MATHEMATICS COURSE SYLLABUS 2020-2021

Course Outline

Overview

The Maths 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 providing a foundation for understanding the world, the ability to reason mathematically, an appreciation of the beauty and power of mathematics, and a sense of enjoyment and curiosity about the subject.

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.

Unit 2 – Equations and formulae

Approximate length: 1 week

In this unit the children will use and interpret algebraic notation, understand and use standard mathematical formulae; rearrange formulae to change the subject, substitute numerical values into formulae and expressions, including scientific formulae and understand and use the concepts and vocabulary of expressions, equations, inequalities, terms and factors.

Specific National Curriculum Objectives Covered:

  • To expand brackets and simplify more complex expressions
  • To factorise more complex expressions
  • To expand and factorise expressions with more than one variable
  • To solve equations where the variable is in the denominator of a fraction

Unit 3 – Polygons

Approximate length: 1 week

In this unit the children will derive and use the sum of angles in a triangle and use it to deduce the angle sum in any polygon, and to derive properties of regular polygons.

Specific National Curriculum Objectives Covered:

  • To work out the sum of the interior angles of a polygon
  • To work out exterior angles of polygons
  • To calculate the interior and exterior angles of regular polygons
  • To work out which regular polygons tessellate

Unit 4 – Using data

Approximate length: 2 weeks

In this unit the children will describe, interpret and compare observed distributions of a single variable through appropriate graphical representation involving discrete, continuous and grouped data; and appropriate measures of central tendency (mean, mode, median) and spread (range, consideration of outliers). They will also learn Construct and interpret appropriate tables, charts, and diagrams, including frequency tables, bar charts, pie charts, and pictograms for categorical data, and vertical line (or bar) charts for ungrouped and grouped numerical data and be able to describe simple mathematical relationships between two variables (bivariate data) in observational and experimental contexts and illustrate using scatter graphs.

Specific National Curriculum Objectives Covered:

  • To infer a correlation from two related scatter graphs
  • To draw a line of best fit to show a correlation
  • To interpret a variety of two-way tables
  • To estimate a mean from grouped data
  • To draw a cumulative frequency diagram
  • To find the interquartile range
  • To plan a statistical investigation

Unit 6 – Pythagoras’ theorem

Approximate length: 1 week

In this unit the children will Apply angle facts, triangle congruence, similarity and properties of quadrilaterals to derive results about angles and sides, including Pythagoras’ Theorem, and use known results to obtain simple proof and Use Pythagoras’ Theorem and trigonometric ratios in similar triangles to solve problems involving right-angled triangles.

Specific National Curriculum Objectives Covered:

  • To use Pythagoras’ theorem in right-angled triangles
  • Using Pythagoras’ theorem to solve problems
  • To use the converse of Pythagoras’ theorem

Term 2

Programme of Study

Term 3

Unit 11 – Solving Equations Graphically

Approximate length: 2 weeks

In this unit the children will use linear and quadratic graphs to estimate values of y for given values of x and vice versa and to find approximate solutions of simultaneous linear equations. They will learn that there are all sorts of different equations that arise from real situations and pupils will meet some examples in this chapter. They will have met straight-line graphs and quadratics before but this chapter builds on this with more complex examples. It will introduce the idea that many equations that are used to model the real world are difficult to solve by algebraic methods and are more easily solved by drawing a graph.

Specific National Curriculum Objectives Covered:

  • To draw any linear graph from any linear equation.
  • To solve a linear equation from a graph.
  • To solve a pair of simultaneous equations by drawing graphs.
  • To solve quadratic equations by drawing graphs.
  • To solve a cubic equation by drawing a graph.

Unit 12 – Compound Units

Approximate length: 1 week

In this unit the children will use standard units of mass, length, time, money and other measures, including with decimal quantities. They will change freely between related standard units [for example time, length, area, volume/capacity, mass]. They will use compound units such as speed, unit pricing and density to solve problems.

Specific National Curriculum Objectives Covered:

  • To understand and use measures of speed.
  • To understand and use density and other compound units.
  • To understand and use unit pricing.

Unit 13 – Right-Angled Triangles

Approximate length: 2 weeks

In this unit the children will learn that trigonometry is the branch of mathematics that studies the relationships between the sides and angles of triangles. This chapter introduces these important properties of right-angled triangles and demonstrates how this can be used in real life situations such as estimating the height of a tree.

Specific National Curriculum Objectives Covered:

  • To understand trigonometric ratios
  • To understand what the trigonometric ratios sine, cosine and tangent are.
  • To find the angle identified from a trigonometric ratio.
  • To find an unknown length of a right-angled triangle given one side and an angle.

Unit 14 – Revision and GCSE Preparation

Approximate length:

In this unit the children will revise over the following mathematical strands:

  • Number
  • Algebra
  • Geometry and measures
  • Statistics

The material will provide excellent practice so that pupils become mathematically fluent. Encourage pupils to work through this whole chapter before their End of Year 9 tests.

Specific National Curriculum Objectives Covered:

  • Help pupils to practise and revise topics covered in their current course.
  • Get pupils started on their foundation to iGCSE course.

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. The learning will be linked to the unit objectives and prior knowledge of the concept. Mathematical concepts like Percentages/ Polygons/ Volume and surface area of cylinders / Algebra would be covered using a blend of online learning and teaching tools using Phoenix,Teams, myimaths, class activities and tasks. Effective learning is encouraged through frequent activities and self-assessment questions.

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.

Summative: At the end of each term we complete internal tests – Unit based and combined Units. Students complete standardized tests. This allows us to measure the students’ progress throughout the term and year. At the end of the academic year, the students sit for the end of year exams.
