Notes:
- ACARA-style content wording is written as curriculum-like fragments (not ACARA code). Use these rows to paste into Excel; you can add ACARA content codes as needed.
- Match Level key: Direct match = topic and cognitive demand are directly covered in that year; Partial match = related content or introductory exposure; Extension/exceeds = topic depth or associated number theory/algebra exceeds typical expectations for that year.
- Common Core notes reference the sets you specified (middle school geometry standards and the HS N-Q, Algebra SSEE/CE, and Statistics interpreting standards) — where I list them as mapping, it indicates conceptual alignment rather than an exact CCSS code-by-code mapping.
If you would like, I can: (a) export this table as a .csv or .xlsx file ready for download; (b) add ACARA content codes beside each row; or (c) produce a condensed single-row-per-subtopic summary (one summary row listing the strongest Year-level match only).
