Collaboration is extremely important for students for many reasons. For example, working with others creates the opportunity for sharing new ideas and problem solving. Communication and critical thinking skills will improve as well with collaboration. I am including a video that shows how to annotate while using Microsoft Teams, and there are many other tutorial videos that are available in the list under the initial video. If a student is having trouble at home or is too shy to ask a question in the classroom, they can easily find these tutorial videos. The students can annotate at the same time as each other, and they can do things such as leave a sticky note with an important reminder, or highlight important information.
