How to use these algebra 1 worksheets
Pick a chapter, read its one-page lesson, then solve the worksheet on paper and check every answer with the solutions page. Take the ten-question quiz to see what is still unclear, and finish with the timed test. Every page can be printed from its PDF button, and the quick practice at the bottom of each page gives ten new questions at every visit.
Algebra 1 math: common questions
What is Algebra 1?
Algebra 1 is usually the first high school math course, taken in 9th grade or earlier. It studies linear, exponential and quadratic functions and the equations that go with them.
What grade is Algebra 1?
Most students take Algebra 1 in 9th grade; strong students take it in 8th grade.
What are the hardest Algebra 1 topics?
Factoring quadratics, solving quadratic equations by completing the square or the quadratic formula, and systems of equations are where students most often need extra practice.
Is there an Algebra 1 practice test?
Yes. Every chapter has a 45-minute test with point values and a solutions page with the scoring guide.
