In Google Classroom, you can now give assignments to all students, individual students, or groups of students just with a few checkboxes. Go to Google Classroom and click on the plus sign to start a new announcement, question, or assignment. When it pops up, you will notice a new drop down menu.....All Students. Here you can decide which students will receive your post. By default, each post is set to All Students. If you would like to only have a few students receive it, click on the All Students drop down menu and select the students that you want to send it to.
