Choose how to start a project
Choose the starting point that gives you useful structure without creating work you will immediately undo.
Start with a Craft Pattern
Section titled “Start with a Craft Pattern”Use a Craft Pattern when the learning arc is clear but the topic, audience, or local context is yours. Filter the gallery by subject, grade, or duration, then preview a pattern before adopting it.
The preview shows the arc and the choices made by Rectangle’s editors. Adoption copies that structure into your draft. Your project can then diverge without later changes to the canonical pattern silently rewriting it.
Start blank
Section titled “Start blank”Choose Start blank when you already know the structure or want to build every part directly. You receive the same five-tab workspace with no milestone or rubric structure prefilled.
Remix a published project
Section titled “Remix a published project”Use Remix when a published project is already close to what your students need. Rectangle preserves the source teacher and project, creates or resumes your private adaptation, and asks you to explain meaningful changes before publishing.
Author with an AI assistant
Section titled “Author with an AI assistant”Use a connected AI assistant when conversation is the fastest way to shape a complete first draft. The assistant may work only within the Authoring scopes you grant. Its result remains a draft that you inspect in Rectangle before it can become classroom-ready or public.
