This guide serves as a chapter-wise companion to the textbook Foundation Mathematics for ICSE Class 9. Each chapter begins with a “Chapter at a Glance” section that highlights the key definitions, formulas and concepts. This is followed by fully worked solutions to all textbook and workbook exercises, and then additional practice sets and model board-pattern questions to reinforce learning and build exam confidence.Chapter 1: Number Systems & Operations – Introduction to integers, fractions, decimals, rational and irrational numbers, with worked problems and example exercises.Chapter 2: Algebraic Expressions & Identities – Simplification of expressions, standard identities, factorisation and step-by-step solutions.Chapter 3: Linear Equations in One & Two Variables – Solving equations, word problems and system of equations with detailed worked-out solutions.Chapter 4: Ratio, Proportion & Percentage – Concepts of ratio, proportion, percentages, change and related applied problems.Chapter 5: Geometry – Lines & Angles – Basic theorems, parallel lines, angles, with diagram-based proofs and solved questions.Chapter 6: Triangles & Its Properties – Types of triangles, angle sum property, similarity, Pythagoras theorem and worked numerical examples.Chapter 7: Coordinate Geometry – Points, coordinates, section & midpoint formula, distance formula and practice sets.Chapter 8: Mensuration – Area & Volume – Areas of plane figures, volumes & surface areas of solid figures with worked problems.Chapter 9: Statistics & Probability Basics – Data collection, mean/median/mode, introduction to probability with solved examples and practice questions.Each chapter is enriched with summary boxes, formula lists and model test papers at the end of the book to match the ICSE exam pattern and build confidence. With its structured layout, comprehensive solved content and focused practice, this guide is an essential tool for self-study, revision and achieving success in the ICSE Class 9 Mathematics examination.
