Equation Balance

How to Play Equation Balance

1. Read the equation on the glowing display and compare both pans.
2. Choose an operation tool and enter a whole-number value.
3. Apply the same operation to both sides to keep the scale balanced.
4. When x is isolated, press Check Solution to substitute and verify.
5. Use Undo, Hint, and the lab history when you need a careful redo.

Learning goals

• Understand equality as balance between two sides.
• Practice inverse operations to isolate a variable.
• Solve one-step and two-step integer equations.
• Check solutions by substitution.

About this game

Help Nova, Bolt, Pip, and Mira run a mechanical equation scale. Add, subtract, multiply, or divide both sides, watch the pans rebalance, verify with substitution, and keep a clear lab history of every valid step.

Controls: keyboard-touch. Scores are verified before appearing on the public leaderboard. Read how scoring works.

Skills practiced

• Algebraic thinking, equality, inverse operations, one-step equations, two-step equations, multiplication and division equations, combining like terms, and checking solutions by substitution.

Scoring tips

• Keep both pans equal, prefer inverse operations, avoid unnecessary steps, save hints for tough equations, and always verify with Check Solution for the substitution bonus.

Difficulty guide

• Easy focuses on one-step addition and subtraction with generous time. Medium adds multiplication, division, and introductory two-step work. Hard includes variables on both sides, distributive forms, and combining like terms with integer solutions only.

Parent and teacher notes

Equation Balance represents equations as physical balance pans for practice and entertainment. Difficulty, session length, and practice category are adjustable. No account is required and score submission is optional. The game is practice, not a formal assessment.
