8th Grade Adding Negative Numbers Quizzes

Start with a number line so students can see addition as movement: adding a positive moves right, while adding a negative moves left. Then connect the model to the rule that integers with the same sign combine and keep that sign, while integers with different signs require finding the difference and keeping the sign of the number with the greater absolute value.

Use a progression of number-line problems, two-integer sums, and multi-step expressions. Mix examples such as −6 + (−3) and −6 + 9 so students must reason about signs instead of applying one rule mechanically.

Students often treat every pair of negative signs as positive, add absolute values when the signs differ, or choose the answer's sign based on the first number. Ask them to estimate whether a sum should be positive or negative before calculating; this catches many sign errors.

Assign a quiz as a digital quiz on Wayground or download the printable PDF for paper practice. Every quiz includes a complete answer key, and teachers using paper copies can scan or capture submissions for grading with the Wayground for Teachers app.

Common Core builds integer addition from earlier work with positive and negative quantities and number-line distance. Students then use signed-number operations to simplify expressions, solve equations, and work with algebraic relationships.

For students who struggle to track signs, create a version with larger text or wider spacing and provide extended time during digital practice. A dyslexia-friendly font can also make multi-step expressions easier to scan without changing the mathematical demand.

Students typically begin formal addition of positive and negative rational numbers in Grade 7 and apply the skill more extensively in Grade 8 algebra. These Grade 8 quizzes are suited to review, remediation, and practice with increasingly complex expressions.
