Yes, for the mathematics — but not course for course. North Carolina teaches an integrated pathway, so NC Math 1, 2, and 3 each mix algebra, functions, geometry, and statistics instead of running Algebra 1, then Geometry, then Algebra 2. Brilliant’s catalog is organized by topic, so a student in NC Math 2 needs pieces of several Brilliant courses, and one Brilliant course usually spans two NC years. What Brilliant does not do is the classroom layer: no proof writing, no pacing guide, no end-of-course practice. Use Brilliant for the math, and your class and NCDPI’s resources for the rest.
The year decides the answer, so the rest of this page is split by course.
Why the fit runs sideways
North Carolina adopted this pathway in 2016, has taught it since 2017–18, and revised its unpacking documents in 2022. Every standard carries its year in the code, and nine of the twenty-three Brilliant courses that map here reach more than one year: Quadratics covers Math 1 and Math 2, Exponential Functions all three.
North Carolina is also not Common Core, even where it derives from it. NC.M1.N.RN.2 asks only for integer exponents, holding rational exponents and radicals back to NC.M2.N.RN.2; NC.M1.A.REI.4 limits quadratic solving to square roots and factoring, with the quadratic formula arriving in NC.M2.A.REI.4.a. Brilliant’s Common Core page is not a substitute for the North Carolina ones.
NC Math 1
The strongest match of the three: linear and exponential functions, quadratic expressions, coordinate geometry, and two-variable statistics all have dedicated courses.
| Brilliant course | What it gets you for Math 1 | Start here |
|---|---|---|
| Linear Expressions & Equations (59 lessons) | Multi-step equations and inequalities, negative and fractional coefficients | Combining Terms |
| Linear Functions (45 lessons) | Slope, intercepts, average rate of change, and the parallel and perpendicular criteria | Change per One |
| Linear Systems (24 lessons) | Substitution, elimination, graphing, and inequality systems as regions of the plane | Graphing Systems of Equations |
| Quadratics (69 lessons) | Polynomial arithmetic, factoring, and solving by factoring or taking square roots | Undistributing |
| Exponential Functions (63 lessons) | Growth and decay, choosing between a linear and an exponential model, end behavior | Growing |
| Introduction to Functions (68 lessons) | Function notation, domain and range in context, reading key features from a graph | Finding the Rule |
The statistics strand sits elsewhere: lines of fit, residuals, and correlation in Regression, from Calculating Error; center, spread, and Outliers in Everyday Statistics; histograms and scatter plots at Observing Relationships.
Get from class: naming and interpreting the parts of an expression in context, justifying a solve step by step in writing, rearranging a science formula for a chosen variable, the midpoint of a segment, and telling association from causation.
NC Math 1 coverage lists every Math 1 standard beside the lessons that teach it.
NC Math 2
Transformations, congruence, similarity, and probability arrive here alongside quadratics — and transformations are the deepest thing Brilliant has for this year.
| Brilliant course | What it gets you for Math 2 | Start here |
|---|---|---|
| Coordinate Transformations (60 lessons) | Translations, reflections, rotations, and dilations by coordinates; congruence and similarity | Reflecting Coordinates |
| Quadratics (69 lessons) | Completing the square, the quadratic formula, vertex form, the axis of symmetry, non-real roots | Completing Any Square |
| Exponents & Radicals (83 lessons) | Rational exponents and radical form — the number work this year adds | Exponent One Half |
| Complex Plane (50 lessons) | The imaginary unit and writing a solution in the form a + bi | The Square Root of -1 |
| Probability and Chance (31 lessons) | Sample spaces, Venn diagrams, the addition and multiplication rules, conditional probability | Venn Diagrams |
Independence is at Dependence and Independence. The right-triangle strand is split: the Pythagorean theorem in Coordinate Geometry, the 30-60-90 and 45-45-90 triangles in Trigonometric Functions.
Get from class: the congruence and similarity criteria — ASA, SAS, SSS, HL, AA — and the theorems proved from them: vertical angles, transversal angles, isosceles base angles, the triangle proportionality theorem. Also building quadratic, square root, and inverse variation equations from a context, line-and-parabola systems, and reading probabilities off a two-way frequency table.
NC Math 2 coverage has the full list.
NC Math 3
Math 3 pulls in polynomial, rational, and logarithmic functions — and a real trigonometric functions cluster. Radian measure, the unit circle, and a sine function’s amplitude, midline, and period are third-course content here, not held back to a fourth year, and Brilliant covers that cluster end to end.
| Brilliant course | What it gets you for Math 3 | Start here |
|---|---|---|
| Equations & Curves (61 lessons) | Rational functions and asymptotes, roots as inverses, transformations, intersections as solutions | Reciprocal Power Functions |
| Polynomials (52 lessons) | Factoring past the quadratic case, roots and factored form, end behavior, counting solutions | Introduction to Roots |
| Trigonometric Functions (62 lessons) | Radians, arc length, the unit circle, sine and cosine as functions, amplitude, midline, and period | The Unit Circle |
| Exponential Functions (63 lessons) | Logarithms, solving an exponential equation with logs, exponentials and logs as inverses | Taking Logs of Both Sides |
| Introduction to Functions (68 lessons) | Piecewise functions, combining functions, deciding whether an inverse exists and writing it | Piecewise Functions |
The circle equation is in Coordinate Geometry; the volume formulas are in Geometry and Measurement.
Get from class: the circle theorems — central, inscribed, and circumscribed angles, and the relationships among radii, chords, secants, and tangents — plus parallelogram theorems, triangle centers, cross sections, and modeling with density. On the algebra side, the Remainder Theorem, rewriting a rational expression as a quotient plus a remainder, and extraneous solutions to rational equations. So is the inference strand: random sampling, margin of error by simulation, and judging a study you read about.
NC Math 3 coverage has the standard-level detail.
If the course you are in assumes math you do not have
A large share of Brilliant’s catalog sits below this framework, in North Carolina’s grades 6–8 course of study, which Math 1 takes as given. Nothing in Fractions, Negative Numbers, Percentages, or Proportional Reasoning maps to a Math 1, 2, or 3 standard for that reason. That is a route in, not a gap: if signed numbers or ratios are costing you points, start there and rejoin the tables above. What Brilliant covers for eighth grade math maps that ground.
A couple of topics sit beside the framework instead of under it: expected value and surface area are taught well on Brilliant, and neither appears anywhere in Math 1, 2, or 3.
What should you use alongside Brilliant?
Your teacher first, NCDPI second. The department publishes the standards with unpacking documents that spell out how far each one goes, plus released test items. NC Math 1 and NC Math 3 both carry an end-of-course assessment, and the Math 1 result counts toward school accountability — which makes NCDPI’s released material, not a commercial prep book, the thing to practice on. Ask your teacher which items are current.
Is Brilliant a complete NC Math course?
No. Brilliant is not affiliated with or endorsed by NCDPI, follows no pacing guide, and has no end-of-course practice. It helps you understand the mathematics behind the course. Use NCDPI’s materials and your class alongside Brilliant for released items, exam-specific practice, and the proof writing these courses ask for.
How this mapping was made
Brilliant’s curriculum team maps each skill to the North Carolina standard it fits most closely, using NCDPI’s standards and unpacking documents as the authority on what each requires. The data was pulled on September 3, 2026 against the live course catalog.
Frequently asked questions
I am in NC Math 2. Can I use Brilliant’s geometry material for it?
Yes, but not as a substitute. Math 2’s geometry is transformation-based — congruence and similarity defined by rigid motions and dilations — which is exactly what Coordinate Transformations teaches. The proof-writing half is not.
Can Brilliant help with the NC Math 1 end-of-course exam?
With the mathematics on it, yes. With the exam itself, no. Work NCDPI’s released items to see how questions are asked, then use Brilliant on the topics they expose.
I am behind. Should I still work the table for my year?
Open the row that matches this week’s topic, but repair what is underneath it first — the section above points at where that ground is.
