This page maps Texas TEKS math student expectations from grade 3 through high school to the Brilliant lessons that teach them. Search by student expectation code or skill to find the closest match. A student expectation is listed only where Brilliant content fully or in part addresses the student expectation directly.
Most codes below end in the expectation letter, as 6.4.H does. A few knowledge statements in Chapter 111 contain a single expectation with no letter at all — 6.11, 7.7 and 8.9 among them — and those are cited here exactly as the rule writes them, without a trailing letter.

How this page is built
Every skill in Brilliant's math skill hierarchy is mapped to the single student expectation it aligns with most closely, using the Texas Essential Knowledge and Skills for Mathematics, 19 TAC Chapter 111 as the authority for what each student expectation requires and where its boundaries fall. Skills that build toward a student expectation without teaching its stated content are excluded, so a skill appears here only where it addresses the student expectation directly.
Each skill links to a lesson where it is practiced, and hovering a skill shows the description learners see for it. This page is regenerated from the mapping, so it reflects the current state rather than a fixed snapshot.
