Subtraction in Equivalent Expressions

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

Expanding and Factoring

• 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.

Combining Like Terms (Part 1)

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

Combining Like Terms (Part 2)

Keeping the Equation Balanced

• I can add or remove blocks from a hanger and keep the hanger balanced.
• I can represent balanced hangers with equations.

Balanced Moves

• 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.

More Balanced Moves

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

Solving Any Linear Equation

• I can solve an equation where the variable appears on both sides.

All, Some, or No Solutions

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

How Many Solutions?

• I can solve equations with different numbers of solutions.
