See below for calendars displaying assignment due dates and test dates posted in Google Classroom. All assignments that are posted in Google Classroom will also be displayed on the calendar. Make sure you are looking at the correct calendar for your student's class. Classes are labeled with the grade, a period, and then the class order. For example, 8.1 is 8th grade 1st activity.
The names of assignments in Google Calendar and Parent Portal will match, but not necessarily the date. Therefore, please be sure to look for the name of the assignment in Google Classroom.
