Solving one-step equations with inverse operations
An equation states that two expressions have equal value. Undo the operation attached to the variable by applying its inverse to both sides. This preserves equality and isolates the unknown.
6th Grade Expressions and Equations Worksheets
Write, read, and evaluate expressions and solve one-step equations.
About Expressions and Equations
Expressions and Equations introduces students to the language of algebra. Students learn to write and evaluate algebraic expressions, apply the order of operations, solve one-step equations, write and solve inequalities, and analyze relationships between variables. These skills form the foundation for all of high school algebra.
Why Expressions and Equations Matters for 6th Grade
For 6th Grade students, transitioning from arithmetic to algebra is one of the most significant cognitive leaps in all of mathematics education. Algebra introduces abstract thinking — the ability to work with unknown quantities symbolically. Every math course from this point forward depends on this foundation.
Learn these skills step by step

Check three selected skills for this grade and use the explained answers to choose your next practice.
Choose an available subtopic
Students first learn to write and evaluate expressions — algebra's equivalent of arithmetic computation. Then they solve equations (finding the exact value that makes a statement true) and inequalities (finding ranges of values). Finally, they connect two-variable relationships to tables and graphs, previewing functions.

1
Help your student see variables as placeholders: "x just means 'some number we don't know yet.'"
2
Practice order of operations with real examples — incorrect PEMDAS is one of the most common algebraic errors.
3
When solving equations, encourage your student to write out every step rather than doing it mentally — this habit prevents errors.
4
For inequalities, ask "would any number greater than 5 work?" to build intuition for solution sets.
5
Connect dependent and independent variables to real-life patterns: "For every hour you work, you earn $12. How many hours and how much money are related?"
Frequently Asked Questions
What skills does expressions and equations cover in 6th Grade?
6th Grade expressions and equations builds foundational skills that students need to progress in math. The worksheets on this page cover the available skills listed below, organized from basic to more advanced.
How many expressions and equations worksheets are available?
Available subtopics have 10 numbered sets for 6th Grade expressions and equations, organized by difficulty level (Easy, Medium, Hard). Each worksheet targets specific skills within this topic area.
What should my student learn before starting 6th Grade expressions and equations?
Check the prerequisite topics listed on this page. We recommend students have a solid understanding of those foundational skills before moving on to expressions and equations.
How do I know if my 6th Grade student is ready for the Hard expressions and equations worksheets?
Start with the Easy worksheets (Worksheets 1–3). If your student completes them confidently with minimal errors, move to Medium (Worksheets 4–7). Reserve the Hard worksheets (Worksheets 8–10) for students who have demonstrated solid mastery at the Medium level. It is perfectly fine to spend more time at a lower difficulty — mastery at each level is more valuable than rushing ahead.
