Unit 1: Further on Sets
This unit helps students understand the structure and classification of sets, including elements, operations, and real-life applications involving set relationships.
Unit 2: The Number System
Students will deepen their understanding of number classifications, including rational, irrational, and real numbers, while revisiting operations with integers and fractions.
Unit 3: Solving Equations
Students develop techniques to solve both linear and non-linear equations, apply algebraic rules, and interpret their solutions in real-world problem contexts.
Unit 4: Solving Inequalities
Through this unit, students become familiar with solving and graphing different types of inequalities including linear, absolute value, and quadratic forms.
Unit 5: Introduction to Trigonometry
The basics of trigonometric ratios are introduced, allowing students to explore relationships in right-angled triangles and apply trigonometry to geometry problems.
Unit 6: Regular Polygons
This unit explores properties of polygons, enabling learners to calculate interior and exterior angles and recognize patterns in regular geometric shapes.
Unit 7: Congruency and Similarity
Students learn to identify congruent and similar figures, use geometric theorems, and apply ratios of sides and areas to solve comparative shape problems.
Unit 8: Vectors in Two Dimensions
This unit introduces vector and scalar quantities, vector representation, and operations, helping students solve problems involving direction and magnitude.
Unit 9: Statistics and Probability
Students are introduced to data collection, interpretation, and probability, helping them make informed predictions and analyze statistical patterns.
