Part of: [New Jersey: Mathematics](https://ai.page/roadmap/nj.md)

Goal: New Jersey academic standards: Mathematics, High school

## 1. Vector and Matrix Quantities · Multiply a vector by a scalar.

- [Plotting Linear Graphs](https://ai.page/c/plotting-linear-graphs/index.md): Plot linear graphs by generating a table of values, reduce a two-variable linear equation to the form y = mx + c, and calculate gradients from two points on a line

## 2. Seeing Structure in Expressions · Choose and produce an equivalent form of an expression to reveal and explain properties of the quantity represented by the expression.

- [Factorising Expressions](https://ai.page/c/factorising-expressions/index.md): Factorise algebraic expressions by taking out common factors — identify the highest common factor of all terms and write the expression as a product, e.g., 6x + 9 = 3(2x + 3)

## 3. Seeing Structure in Expressions · Interpret expressions that represent a quantity in terms of its context.

- [Percentages as Fractions](https://ai.page/c/percentages-as-fractions/index.md): Define percentage as 'number of parts per hundred'; interpret percentages and percentage changes as a fraction or a decimal; express one quantity as a percentage of another; compare quantities using percentages; work with percentages greater than 100%

## 4. Reasoning with Equations and Inequalities · Solve quadratic equations in one variable.

- [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

## 5. Linear and Exponential Models · Distinguish between situations that can be modeled with linear functions and with exponential functions.

- [Linear Function Graphs](https://ai.page/c/linear-function-graphs/index.md): Recognise that a linear function produces a straight-line graph, understand the relationship between an equation of the form y = mx + c and its graphical representation, and interpret gradient and y-intercept in context

## 6. Interpreting Functions · Write a function defined by an expression in different but equivalent forms to reveal and explain different properties of the function.

- [Quadratic Graphs](https://ai.page/c/quadratic-graphs/index.md): Recognise that quadratic functions produce curved (parabolic) graphs, distinguish them from linear graphs, and use plotted quadratic graphs to estimate values and find approximate solutions

## 7. Building Functions · Find inverse functions.

- [Using inverse operations](https://ai.page/c/using-inverse-operations/index.md): Recognise and use relationships between operations including inverse operations; use these relationships to check answers and simplify calculations
- [Simple formulae](https://ai.page/c/simple-formulae/index.md): Understand and use standard mathematical formulae; rearrange formulae to change the subject, performing inverse operations to isolate a different variable

## 8. Building Functions · Write a function that describes a relationship between two quantities.

- [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

## 9. Similarity, Right Triangles, and Trigonometry · Verify experimentally the properties of dilations given by a center and a scale factor:

- [Coordinates (age 12+)](https://ai.page/c/coordinates-age-12/index.md): Understand similarity as a relationship where one shape is an enlargement of another; construct similar shapes by enlargement with a given scale factor and centre, with and without coordinate grids

## 10. Using Probability to Make Decisions · Weigh the possible outcomes of a decision by assigning probabilities to payoff values and finding expected values. For example, find the forecasted value of an in

- [Estimating by rounding](https://ai.page/c/estimating-by-rounding-maths/index.md): Use approximation through rounding to estimate answers and calculate possible resulting errors expressed using inequality notation a < x ≤ b; understand upper and lower bounds of rounded values

## 11. Interpreting Categorical and Quantitative Data · Represent data on two quantitative variables on a scatter plot and describe how the variables are related.

- [Scatter Graphs & Correlation](https://ai.page/c/scatter-graphs-and-correlation/index.md): Describe simple mathematical relationships between two variables using scatter graphs, identify positive, negative, or no correlation, and use a line of best fit to make predictions
