Free 8th Grade Math Worksheets
Eighth grade is the doorway to algebra, and its arithmetic demands are correspondingly sharp. Students work extensively with exponents — squares, cubes, powers of 10, and negative bases — while keeping integer operations, complex fractions, and multi-step expressions fluent. These worksheets provide the rigorous computational practice that makes Algebra 1 feel manageable instead of overwhelming.
Key Skills at This Level
- Evaluating exponents: squares, cubes, and higher powers
- Powers of 10 and the foundation for scientific notation
- Exponents with negative bases
- Fluent operations with negative integers
- Mixed operations across fractions and decimals
- Challenging multi-step order of operations

Exponents Take Center Stage
Exponents are the defining computational skill of eighth grade: they power scientific notation, exponent rules, and eventually exponential functions. The worksheets here build from memorizing the squares and cubes every algebra student needs on instant recall, through powers of 10, to expressions with negative bases — where the difference between (−3)² and −3² separates students who understand notation from students who guess.
Keeping the Foundations Sharp
Algebra 1 assumes integer fluency so completely that a sign error can hide inside every solved equation. That is why this page keeps intermediate and advanced integer work alongside the exponent material, plus the most challenging fraction and decimal mixed-operation sets in our library — the exact arithmetic that appears inside algebraic manipulation.
Algebra Readiness You Can Check
A simple readiness test: hand an eighth grader one challenge worksheet from each category on this page. Wherever accuracy drops below roughly nine in ten, that skill deserves a week of short daily practice before it costs points in Algebra 1. The included answer keys make the whole diagnostic take one sitting.
Frequently Asked Questions
What math do 8th graders learn?
Eighth grade covers exponents and scientific notation, linear equations and functions, and geometry concepts like the Pythagorean theorem. These worksheets drill the computational backbone — exponents, integer operations, and multi-step arithmetic — that all of it depends on.
What is the difference between (−3)² and −3²?
(−3)² squares the entire quantity negative three, giving 9. Without parentheses, −3² means the negative of 3², giving −9. Reading exponent notation precisely is a core 8th grade skill, and the negative-base worksheets here target it directly.
How do I know if my 8th grader is ready for Algebra 1?
They should be quick and accurate with integer sign rules, fraction and decimal operations, exponents, and multi-step order of operations. Use the hardest worksheet in each category on this page as a diagnostic — consistent accuracy means the arithmetic will not get in algebra's way.
