Hi @michael.wesley,
All of the worksheets (or pretty much all – I haven’t accessed every single one) are linked in the curriculum as Google Docs. You can make a copy & set it so that your students can make their own editable copies to submit for grading. For group assignments they can work on one doc with multiple editors, but that has a host of other issues that would have to be worked through (same as it would for any class).
Is anyone else here in a similar situation & able to weigh in on options?
