Functions and Change Lesson Set
Use the functions topic page, the existing graph-first starter track, one accumulation checkpoint, and the calculus topic page so the early math branch stays compact for a teacher-led lesson block.
This lesson set is for the moment when the new math slice should feel like one real path instead of separate shelves. It starts with the functions topic page for orientation, uses the authored Functions and Change starter track for the main order, closes with the accumulation checkpoint already shipped inside that track, and then hands off to the calculus topic page so the next branch stays visible.
