precalculus

Non-honors Precalculus: 8 units × 8 lessons. See COURSE_PLAN.md for the unit/lesson map, content sources, and the reauthoring checklist.

Getting the source

math-shared/ is a git submodule, code-layne/math-shared, which holds the grading package shared across the courses. It sits at the project root, not under shared/: the build searches shared/ recursively, and math-shared/examples holds main.tex files a component build would pick up. Clone with it:

git clone --recurse-submodules https://github.com/code-layne/precalculus

In a clone made without --recurse-submodules, run git submodule update --init once. Ordinary builds still work without the submodule; only components that load grading and the grading targets below need it.

Graded components

A component that loads grading (from math-shared/grading.sty) marks its graded answers with \gradedblank. Each page then carries corner registration marks, a QR code, and an id strip (ID: <tracking id>). Graded pages never carry a student name. Each \gradedblank line is written identically in the blank and the key; the key prints the answer inside the box (precalculus-key turns this on whenever a document loads grading). See math-shared/README.md for the macros and math-shared/grading-system-design.md for the plan, and the "Graded components" section of LESSON_SHAPE.md for which components are graded and how their assignment ids are formed.

# a lesson component: manifest.json, and the check that blank and key agree
make -C unit03/lesson01 manifest COMP=homework
# per student: the lesson packet with her name on the cover and her copy of every graded component
make -C unit03/lesson01 roster-packets ROSTER=~/Mathematics/rosters/roster-map.csv SECTION="Precalculus"

# a unit test (also runnable from tests/ or test_keys/ with the bare name)
make -C unit01 manifest COMP=tests/practice_test
make -C unit01 roster-packets COMP=tests/actual_test ROSTER=~/Mathematics/rosters/roster-map.csv

# the same from the root
make roster-packets LESSON=unit03/lesson01 ROSTER=~/Mathematics/rosters/roster-map.csv
make roster-packets COMP=unit01/tests/actual_test ROSTER=~/Mathematics/rosters/roster-map.csv
make manifest COMP=unit01/lesson02/ap_practice

Scanned pages go to an outside service, so a graded page carries only the student's tracking id. In a lesson packet the name is printed on the Name line of the lesson cover. Every graded component (AP Practice, a printed homework) starts on a fresh sheet, so the student tears those sheets out and turns them in, and the cover stays in her packet. The lesson's roster PDF is target/compiled/unitXX/lessonYY_roster.pdf, one packet per student in roster order, paginated like make student. A test instead gets math-shared's tear-off name sheet: each student's run (name sheet, blank back, copy, and a blank page if the copy is odd) is even, so every name sheet starts on an odd page when the roster PDF prints duplex. Both builds write each graded component's manifest.json first, which grading ingest reads. SECTION= builds one section. The roster PDFs hold names, so they stay under target/, which is never committed; the build fails if a name reaches a graded page. Keep roster-map.csv outside the repository.
