Grade 9 – Mathematics

Welcome to Grade 9 Mathematics, your very first year in secondary school — an exciting new stage in your academic journey! Mathematics at this level is more than just numbers; it is the language of logic, patterns, and problem-solving. This course is designed to be the most comprehensive, reliable, and student-friendly guide to mastering the official Ethiopian Ministry of Education curriculum.

Throughout Grade 9, you will explore nine major units: Sets, the Number System, Solving Equations, Solving Inequalities, Introduction to Trigonometry, Regular Polygons, Congruency and Similarity, Vectors in Two Dimensions, and Statistics & Probability. Each unit introduces essential concepts that connect directly to real-world applications, while also preparing you for higher-level mathematics in Grades 10–12. For example, the study of sets helps you understand the structure of relationships, while trigonometry lays the groundwork for advanced geometry and physics.

At WeLearn.et, we understand that students come from different learning backgrounds. That’s why our platform uses spiral learning — constantly revisiting past concepts from primary grades to strengthen your foundation while introducing new, more advanced ideas. No student is left behind; we make sure gaps are filled, and confidence is built.

But learning mathematics shouldn’t feel overwhelming — it should feel engaging. With interactive video lessons, gamified quizzes, real-life problem simulations, and AI-powered personalized learning paths, WeLearn.et transforms every lesson into an exciting discovery. You won’t just memorize formulas — you’ll experience them, practice them, and master them in a way that sticks. This isn’t just about passing your final school assessments; it’s about building problem-solving skills that will serve you for life.

Our Teaching Philosophy: The 7Cs in Action

At WeLearn.et, we design every lesson to build not only academic success but also 21st-century skills using the 7Cs Framework.

Critical Thinking in Action: In our Solving Inequalities unit, you won’t just practice algebraic manipulation. Instead, you’ll analyze real-world inequality problems — like comparing costs and resources — and justify your solutions step by step.

Computing & Digital Literacy in Action: In our Statistics and Probability unit, you’ll use interactive graphing tools to create histograms and probability simulations, learning how digital tools make data analysis clearer and more exciting.
