Build an Algebra 1 pathway

9th grade math worksheets

Move from multi-step equations into functions and linear models, then connect systems and quadratic representations. Course sequences vary, so use the groups as a readiness path rather than a fixed calendar.

21 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-number arithmetic, fraction operations and one- or two-step equations are reasonably secure. If calculation errors hide the algebra, revisit the Grade 7 rational-number group before adding more symbolic steps.

Discuss together

Solve 3(x − 2) + 5 = 14.

x = 5

Distribute first: 3x − 6 + 5 = 14. Combine constants to get 3x − 1 = 14, add 1 to both sides, then divide by 3. Substitution checks the result: 3(5 − 2) + 5 = 14.
