In Google Classroom, where can teachers post announcements?

In Google Classroom, teachers can post announcements in the Stream. The Stream functions as a central hub where teachers and students can engage through posts, announcements, and class discussions. When an announcement is made in the Stream, it appears at the top, making it easily visible to all class participants. Teachers can share important updates, reminders, or general information using this feature, fostering a collaborative environment and ensuring that students are informed about class-related matters.

The other choices have distinct purposes: the Dashboard provides an overview of the teacher's classes and activities, Assignments focus specifically on tasks or work given to students, and Calendar is used to keep track of important dates and events. Each of these options has its utility but does not serve the primary function of sharing announcements, which is best accomplished in the Stream.
