Part of: [NaCCA: Mathematics](https://ai.page/roadmap/gh-nacca.md)

Goal: Senior High School curriculum (NaCCA): Mathematics, SHS 2

## 1. NUMBERS FOR EVERYDAY LIFE · PROPORTIONAL REASONING

- [Proportional Reasoning Vocabulary](https://ai.page/c/proportional-reasoning-vocabulary/index.md): Know and use advanced vocabulary of multiplicative reasoning — direct proportion, inverse proportion, ratio, rate, unit rate, compound unit, scale factor — accurately in problem-solving contexts

## 2. NUMBERS FOR EVERYDAY LIFE · ratios, rates and proportions

- [Ratio Notation and Relationships](https://ai.page/c/ratio-notation-and-relationships/index.md): Understand that a multiplicative relationship between two quantities can be expressed as a ratio; use ratio notation; simplify ratios

## 3. ALGEBRAIC REASONING · APPLICATIONS OF EXPRESSIONS, EQUATIONS AND INEQUALITIES

- [Solving Linear Equations](https://ai.page/c/solving-linear-equations/index.md): Use algebraic methods to solve linear equations in one variable, including equations that require rearrangement, expanding brackets, and collecting terms on both sides; solve equations with rational number coefficients

## 4. simultaneous equations involving two variables

- [Simultaneous Equations](https://ai.page/c/simultaneous-equations/index.md): Understand that two linear equations can be solved simultaneously by finding the point where their graphs intersect, and interpret this graphically and algebraically as the pair of values satisfying both equations

## 5. ALGEBRAIC REASONING · Sequences and Series

- [Generating Sequences](https://ai.page/c/generating-sequences/index.md): Generate terms of a sequence from a term-to-term rule (e.g., 'add 3 each time') or a position-to-term rule (e.g., '2n + 1'), and identify whether a sequence is arithmetic, geometric, or neither

## 6. 3. GEOMETRY AROUND US · 1. SPATIAL SENSE

- [Coordinate Transformations](https://ai.page/c/coordinate-transformations/index.md): Identify properties of translations, rotations, and reflections; describe and perform these transformations on given figures, and understand that the image is congruent to the original

## 7. Trigonometry

- [Trigonometry basics](https://ai.page/c/trigonometry-basics/index.md): Use the trigonometric ratios sin, cos, and tan in right-angled triangles to find unknown sides and angles, including setting up the correct ratio for a given problem
