This google doc has many different resources for many different grade levels and content areas. Please don't just share the link with your students or their parents. This is here for you to do your own research to see if there is a site that can help you with a lesson that is appropriate for your students. What ever you choose, make sure your students have access to the materials that the students need in order to complete the activity. I know that some of them require story books that go with them. I know that a lot of authors are reading their books on video and posting them on Youtube. That would probabaly be they best way to enure the students have the book they need. You would just need to include that Youtube link with the activity instructions that you send to your students.
