### 1: The student will graph and solve linear equations and inequalities in problem-solving situations.

#### 1.1: Equations

1.1.a: Model, write, and solve 2-step linear equations using a variety of methods.

1.1.b: Graph and interpret the solution to linear equations on a number line with one variable and on a coordinate plane with two variables.

1.1.c: Predict the effect on the graph of a linear equation when the slope changes (e.g., make predictions from graphs, identify the slope in the equation y = mx + b and relate to a graph).

#### 1.2: Inequalities

1.2.a: Model, write, and solve 1-step and 2-step linear inequalities with one variable.

1.2.b: Graph the solution to linear inequalities with one variable on a number line.

### 2: The student will use numbers and number relationships to solve problems.

#### 2.1: Rational Numbers and Proportional Reasoning

2.1.a: Compare and order rational numbers (positive and negative integers, fractions, decimals) in real-life situations.

2.1.b: Use the basic operations on rational numbers to solve problems in real-life situations (e.g., describe the effect of multiplying whole numbers by a fraction or a decimal less than 1).

2.1.c: Apply ratios and proportions to solve problems.

#### 2.2: Exponents

2.2.c: Use estimation strategies (e.g., rounding) to describe the magnitude of large numbers and numbers less than one.

### 5: The student will use data analysis and statistics to interpret data in a variety of contexts.

#### 5.2: Measures of Central Tendency

5.2.a: Find the measures of central tendency (mean, median and mode) of a set of data and understand why a specific measure provides the most useful information in a given context.

5.2.b: Compute the mean, median, and mode for data sets and understand how additional data in a set may affect the measures of central tendency.

#### 5.3: Determine how samples are chosen (random, limited, biased) to draw and support conclusions about generalizing a sample to a population (e.g., is the average height of a men’s college basketball team a good representative sample for height predictions?).
