Each page keeps the expectation’s official code — B2.3, D2.4, and so on
— and every lesson, investigation, and task in this course links back to the
codes it addresses. The codes are also tags, so every page tagged #B2 can be
gathered in one place.
Why the codes matter more than they look
A code is a shared address. When a student asks “why are we doing this?”, the answer is a link. When a department writes a course outline, or a teacher takes over a class partway through, the codes are what make one person’s planning legible to another.
