The very first thing you need to do is go to Google Classroom. Now you need to create your first class.
After you have completed your class information it is time to create your first classwork and assignment. Click your class, then at the top, click on Classwork.
Now you just have to add your child into your class. You can invite them by email, or you can have them join the class with the class code that appears in the classroom header.
Google Classroom allows me to plan ahead, and not have to tell them what to do next, and then what to do next. That independence is worth a lot.
Once you have Classroom set up it gives you, the homeschool parent, time to work with other children.
