Trello can make tracking easier. You can post assignments or tasks for the week. Students can interact with each other and leave notes/questions about the task.
Have students get creative and create their own logo! Maybe challenge students for a Virtual Spirit Week and create a logo that represents what they’re feeling or have been doing at home.
Padlet is another great resource for contributing in a group setting. Questions can be posted and Padlet allows you to interact with it.
Kahoot! via WebEx/Zoom with your class could be a very positive class bonding activity. Students have phone and may be keeping in contact that way. However, what about when they get together, see each other, and compete against each other?
TedEd has a variety of educational videos for all students of any age. We especially like it for the way TedEd presents the information in cool, engaging videos.
