We currently have no way of hiding assigned activities from the students. All assigned activities are available for the students to complete them.
What you can do instead is assign due dates for the activities and ask your students to complete them in order of due date. You can also wait to assign the activities until you would like them to be completed.
Have more questions?
Please feel free to live chat with us through the green message bubble on the bottom right corner of the screen or email us at email@example.com.
