Eighth-grade math (ages 13 to 14) introduces the Pythagorean theorem, irrational numbers, linear functions, simultaneous linear equations, and bivariate data. Common Core, the National Curriculum in England (Year 9), the Australian Curriculum (Year 8), and provincial curricula in Canada all share linear functions and the Pythagorean theorem as grade-8 milestones. Our grade-8 content covers slope and linear equations, systems of two equations, the Pythagorean theorem, and scatter plots — strong preparation for algebra 1.

Grade pages are a starting point, not a rigid boundary. Children are commonly ahead in one area and still consolidating in another, and that is normal. If Grade 8 feels too easy or too hard once you look inside, move up or down a grade, or stay here and pick the single skill your child needs — the label matters far less than the practice.
Grade 8 content on this site covers these strands. Open a topic to practise it at any level.
Nothing is locked. Move to the grade that matches what your child is working on today.
