8th grade math worksheets

Connect real numbers and exponent rules to equations, then read and write linear relationships before applying right-triangle and transformation reasoning.

22 printable resources, grouped by skill. Start where the learner is ready; grade expectations vary by school and curriculum.

A useful starting point

Begin when signed arithmetic and one- or two-step equations are reasonably secure. If most errors come from integer operations, use the Grade 7 rational-number group before adding multi-step equation structure.

Discuss together

What is the slope of the line through (−2, 1) and (4, 10)?

3/2

The vertical change is 10 − 1 = 9 and the horizontal change is 4 − (−2) = 6. Divide in the same point order: slope = 9/6 = 3/2. The positive result matches a line that rises from left to right.
