This document provides a complete lesson-by-lesson mapping of Brilliant's courses to Common Core State Standards (CCSS-M) and Next Generation Science Standards (NGSS). Search for any standard code (e.g., 3.NF.1, 7.G.5, HS-PS3-4) to find which Brilliant lessons address it.
How to use this guide
- Search this page (Ctrl/Cmd+F) for any standard code to find aligned lessons
- Standard codes follow these formats:
- Common Core Math: Grade.Domain.Standard (e.g., 3.NF.1 = Grade 3, Number & Operations—Fractions, Standard 1)
- Common Core High School: HS.Domain.Standard (e.g., HSF.IF.2 = High School Functions, Interpreting Functions, Standard 2)
- NGSS Science: HS-Domain-Standard (e.g., HS-PS3-4 = High School Physical Science, Energy, Standard 4)
- Grade levels or subjects show which grades or subjects each lesson is appropriate for (see What grade levels does Brilliant cover?)
For an overview of standards alignment, see Is Brilliant aligned with Common Core? or browse the complete course catalog.
Note: Teachers can also access a searchable course database at educator.brilliant.org/courses showing topics covered in each lesson. We currently do not provide additional standards alignment guides beyond this document, but we do share the topics covered in each course.
