Which app is like an online whiteboard that allows students to include various multimedia sources, items from Drive, and annotate them?

Google Jamboard is designed specifically to function as an interactive online whiteboard, making it an excellent tool for collaborative learning. It allows users to create a digital workspace where they can annotate, draw, and incorporate a variety of multimedia elements such as images, videos, and links directly from Google Drive. This capability makes it ideal for students who want to brainstorm ideas, work on projects together in real time, and visualize concepts using different types of content.

In contrast, Google Docs and Google Slides serve different primary functions. Google Docs is focused on text-based document creation and editing, while Google Slides is tailored for presentations. Both of these tools may allow for some collaborative features but do not provide the same immersive visual and interactive environment as Jamboard. Google Meet, on the other hand, is a video conferencing app that supports meetings and online discussions, lacking the collaborative and multimedia aggregation features offered by Jamboard. Thus, Jamboard stands out as the app that encompasses the full range of functionalities mentioned in the question.
