8th Grade Properties of Equality Quizzes

In 8th grade, students apply the properties of equality to solve linear equations with variables on both sides of the equal sign. This requires a more strategic application of the addition and subtraction properties to collect and isolate variable terms, a core concept in the 8th-grade Common Core standards.

Frame the process as building a logical argument or a 'proof' for their solution. This perspective shifts the focus from just getting the right answer to constructing a valid mathematical case, which is a crucial skill for high school geometry and advanced algebra.

A common mistake is incorrectly trying to 'cancel' a variable term on one side without applying the addition or subtraction property of equality. For example, in 5x = 2x + 9, a student might incorrectly cross out the '2x' instead of subtracting 2x from both sides of the equation.

These quizzes feature a range of linear equations, including those with variables on both sides, those requiring use of the distributive property, and those with special solutions (no solution or infinite solutions). This variety ensures students can apply the properties in diverse scenarios.

For focused, offline practice, assign the printable PDF version of the quiz. After students complete their work, you can use the Wayground for Teachers app to quickly scan and grade their paper submissions using the quiz's answer key.

Wayground's digital format allows for easy differentiation. For students needing support, use the 'Read Aloud' feature to help them process the problem statement. For an extra challenge, you can create a custom quiz version with more complex rational coefficients or problems that require combining multiple like terms before applying the properties of equality.
