Bring on the algebra! Learn how to manipulate expressions and solve equations and inequalities.
Students solve real-life and mathematical problems using numerical and algebraic expressions and equations. Their work with expressions and equations is applied to finding unknown angles and problems involving area, volume, and surface area."
Combining like terms with negative coefficients & distribution. Equivalent expressions: negative numbers & distribution. Expressions, equations, and inequalities: Unit test.
Expressions are combinations of variables and numbers, while equations equate two expressions. Variables can take on different values depending on the context, and we can evaluate expressions by substituting values for the variables.

Solve word problems leading to equations of the form px + q = r and p(x + q) = r, where p, q, and r are specific rational numbers. Solve equations of these forms fluently. Compare an algebraic solution to an arithmetic solution, identifying the sequence of the operations used in each approach.
A variable is a symbol that represents a value, often one that changes, like how long you've been awake. Learn ways that we can change an expression's value (such as by changing the values of its variables) or keep the value the same (such as with the distributive property).
One-step multiplication & division equations: fractions & decimals. Evaluating expressions with variables word problems. Evaluating expressions with multiple variables: fractions & decimals.
