Here is an excellent collection of Computer Science (CS) activities to do at home from Code.org. Perhaps it is a good idea to start from the very basic – CS Fundamentals. There are activities for all ages. Some are unplugged activities and suggestions are available on how to do it. There are extra resources and additional links to other websites if you are looking for more learning choices. A lot of support for teachers, students and families are available on Code.org. I have embedded the introduction video from the founder Hadi Partovi. You can access the resources here.
