A teacher is iterating with Claude on a new unit plan over several weeks. Each time, she opens a fresh chat and re-explains the class, curriculum goals and earlier decisions, and the drafts keep drifting from what was agreed. What is the most appropriate change?

Answer: A — Create a Project with the unit's goals in the instructions and the curriculum documents as knowledge, and iterate there.

A Project gives every chat the same instructions and reference material, so iterations start from shared context instead of re-explanation (a). Repeating everything manually (b) is error-prone and is what's already failing. Asking Claude to remember (c) isn't a dependable substitute for configured context, and memory availability depends on settings. Forcing it into one session (d) doesn't suit work that naturally spans weeks.
