Maths study guides

A deep-dive NC Math 1 EOC guide to coordinate geometry and reasoning (Geometry, about 8 to 12 percent of the test). Covers slope criteria for parallel and perpendicular lines, coordinate proofs about triangles and quadrilaterals, the distance formula, partitioning a directed segment in a given ratio, and the midpoint formula.

A deep-dive NC Math 1 EOC guide to descriptive statistics (Statistics and Probability, about 18 to 20 percent of the test). Covers representing one-variable data with dot plots, histograms, and box plots, comparing center and spread, two-way frequency tables, scatter plots and lines of best fit, and the correlation coefficient with the correlation-versus-causation caution.

A deep-dive NC Math 1 EOC guide to the Expressions and Operations strand (Number and Quantity and Algebra, part of the largest reporting block). Covers interpreting the parts of an expression, rewriting by structure, polynomial operations, factoring quadratics, radicals and rational exponents, and classifying rational and irrational numbers.

A deep-dive NC Math 1 EOC guide to functions and exponential models (the Functions block, about 32 to 36 percent of the test). Covers function notation, domain and range, interpreting key features, average rate of change, arithmetic and geometric sequences, exponential growth and decay, comparing function families, and solving quadratic equations.

A deep-dive NC Math 1 EOC guide to linear equations and functions (Algebra and Functions, the largest reporting block). Covers solving linear equations and inequalities, the flip rule, creating equations and inequalities from context, rearranging formulas, finding slope, writing linear equations, and graphing lines and their intercepts.

A deep-dive NC Math 1 EOC guide to systems of equations and inequalities (Algebra). Covers solving systems by substitution and elimination, solving by graphing and why intersections solve f(x) equals g(x), why equivalent systems work, graphing linear inequalities as half-planes, and modeling situations with systems and constraints.
