Homework is tied to a lesson: text, files, and three settings. One assignment per lesson.
To add and configure homework, open the Courses section, select the course and the desired lesson, open it for editing, and go to the Homework tab, then click "+ Assignment." Enter the text and, if necessary, upload materials. There are three checkboxes: "Important Assignment" (participates in stop lessons), "Automatic Credit" (your answer receives credit immediately), and "Show All" (completed assignments are visible to other students). Save.
Answers are checked on the Homework Check screen in the course's bottom navigation. Lesson quizzes are configured below, on the same tab—see quiz cards.
