Demonstrate fluency with writing and evaluating expressions, combining like terms, solving one-step equations, and modeling with equations.
This checkpoint reviews the whole expressions-and-equations unit: translating words, evaluating with substitution, combining like terms, solving one-step equations, inequalities, and modeling real situations.
As always, read carefully, name what the problem is asking for, and choose the right tool - translating, evaluating, simplifying, or solving.
Mastery looks like: They accurately translate, evaluate, simplify, and solve across a mixed review of expressions and equations.
Common stumbles: Confusing "evaluate," which substitutes a value, with "solve," which finds the unknown value; sign or inverse-operation errors under mixed-review conditions.
