### Lesson 1

- I can graph inequalities on a number line.
- I can write an inequality to represent a situation.

### Lesson 2

- I can determine if a particular number is a solution to an inequality.
- I can explain what it means for a number to be a solution to an inequality.
- I can graph the solutions to an inequality on a number line.

### Lesson 3

- I can explain what the solution to an inequality means in a situation.
- I can write inequalities that involves more than one variable.

### Lesson 4

- I can describe the solutions to a inequality by solving a related equation and then reasoning about values that make the inequality true.
- I can write an inequality to represent a situation.

### Lesson 5

- I can graph the solutions to an inequality on a number line.
- I can solve inequalities by solving a related equation and then checking which values are solutions to the original inequality.

### Lesson 6

- I can use what I know about inequalities to solve real-world problems.

### Lesson 7

- I can organize my work when I use the distributive property.
- I can re-write subtraction as adding the opposite and then rearrange terms in an expression.

### Lesson 8

- I can organize my work when I use the distributive property.
- I can use the distributive property to rewrite expressions with positive and negative numbers.
- I understand that factoring and expanding are words used to describe using the distributive property to write equivalent expressions.

### Lesson 9

- I can figure out whether two expressions are equivalent to each other.
- When possible, I can write an equivalent expression that has fewer terms.

### Lesson 10

- I am aware of some common pitfalls when writing equivalent expressions, and I can avoid them.
- When possible, I can write an equivalent expression that has fewer terms.

### Lesson 11

- Given an expression, I can use various strategies to write an equivalent expression.
- When I look at an expression, I can notice if some parts have common factors and make the expression shorter by combining those parts.

### Lesson 12

- I can add, subtract, multiply, or divide each side of an equation by the same expression to get a new equation with the same solution.

### Lesson 13

- I can make sense of multiple ways to solve an equation.

### Lesson 14

- I can solve linear equations in one variable.

### Lesson 15

- I can determine whether an equation has no solutions, one solution, or infinitely many solutions.

### Lesson 16

- I can solve equations with different numbers of solutions.

### Lesson 17

- I can use an expression to find when two things, like height, are the same in a real-world situation.

### Lesson 18

- I can write algebraic expressions to understand and justify a choice between two options.
