Canvas provides ways to design and organize materials in many ways: via files, modules, pages, the syllabus, etc. One of the best ways to organize material is in modules. Modules act as folders; they allow you to chunk materials and assessments together by topic week.
Chunking material (putting it into sections, on separate pages, etc.) is a helpful way for people to see patterns and make connections between concepts. Chunking materials also helps separate longer lessons into smaller pieces with the scaffolding necessary to support success.
