🔢 Basic Inequalities
In algebra, a variable (like x or y) stands for an unknown number. Use inverse operations to find its value.
2. 3y = 21 → y =
3. n - 6 = 9 → n =

About This Basic Inequalities — Algebra
This free printable basic inequalities worksheet introduces algebraic thinking through patterns, variables, and simple equations. Students learn to find unknowns and balance equations, building a bridge from arithmetic to algebra.
What Students Will Learn
Students learn to identify patterns, use variables to stand for unknown values, and solve one- and two-step equations. They practice writing expressions and understanding that the equals sign means balance, not just "the answer is."
How Teachers Can Use This Worksheet
- Pattern extension: Start with growing patterns and have students describe the rule before introducing symbols — the rule is the first "variable."
- Balance scale model: Use a balance scale or drawings to show that both sides of an equation must stay equal when you add or subtract.
- Word-problem translation: Practice turning simple word problems into equations so students see the purpose of variables.
How Parents and Homeschoolers Can Use This Worksheet
Play "what is the missing number?" games — "3 + ? = 10." Notice patterns in daily life (tiles, stairs, calendars) and ask your child to describe the rule. Keep it playful; the goal is comfort with the idea of an unknown.
