Grade 8 Mathematics
Build confidence with clear notes, worked examples, independent practice and quick knowledge checks. Topics are curriculum-neutral foundations; follow your school's sequence where it differs.
Learning path: Start with number skills, then algebra and geometry. Each lesson includes a five-question quiz and printable practice.
Exponents, Powers and Scientific Notation
Understand integer exponents, exponent laws, powers of ten and scientific notation with worked examples, practice and a quiz.
Study lesson →AlgebraLinear Equations and Inequalities
Solve multi-step linear equations and inequalities, check solutions and represent solution sets on a number line.
Study lesson →GeometryPythagorean Theorem and Right Triangles
Use the Pythagorean theorem to find missing side lengths, test right triangles and solve practical distance problems.
Study lesson →Algebra & functionsLinear Functions and Graphs
Understand linear functions, input-output tables, slope, y-intercepts and straight-line graphs.
Study lesson →AlgebraSystems of Linear Equations
Solve pairs of linear equations using graphs, substitution and elimination, then interpret the solutions.
Study lesson →GeometryTransformations, Congruence and Similarity
Explore translations, reflections, rotations, congruent figures, similar shapes and scale factors.
Study lesson →Geometry & measurementVolume of Cylinders, Cones and Spheres
Calculate the volume of cylinders, cones and spheres, use correct units and solve practical problems.
Study lesson →StatisticsScatter Plots and Data Relationships
Read scatter plots, describe correlation, identify outliers and use lines of best fit with caution.
Study lesson →Statistics & probabilityProbability Models and Compound Events
Use probability scales, sample spaces, complementary events and simple compound-event models.
Study lesson →Number & operationsSquare Roots and Irrational Numbers
Estimate square roots, classify rational and irrational numbers, and compare real numbers on a number line.
Study lesson →GeometryAngle Relationships and Parallel Lines
Use angle facts for intersecting and parallel lines, transversals, triangles and polygons to find missing angles.
