A lesson is built from content blocks. Open a lesson from the curriculum, then use Add Content Block to insert a video, text, PDF, audio, HTML, a resource file, a quiz or an assignment. The lesson's type follows the last main block you added, and that type decides what the lesson needs before it can be published.

|---|---|---|
| Video | An uploaded video, or a YouTube or Vimeo link. | A video. |

| Assignment | Work students hand in for marking. | A saved assignment. |
