Why can't I share my small group assignment to Google Classroom?

Currently, CommonLit does not support posting individual student/small group assignments to Google Classroom streams.

As a workaround, you can use the "Copy Link" feature on CommonLit's share assignment window to copy the assignment link of a small-group assignment. Then, you can manually create a corresponding small-group assignment in Google Classroom assigned to the same students and attach CommonLit's assignment link.
