1. Hover over the "+" button in the lower right hand corner of your classroom and choose create assignment.
2. It should open a dialogue box that looks like this:
3. Add the title of the assignment, the instructions for the assignment, and choose a due date, or no due date.
4. Below the due date, there are four buttons. This is what they all do:
5. From there, you can choose to trash the assignment, assign the assignment immediately, or if you choose the dropdown arrow next to "Assign" you can choose a date and time in the future. You might also have an option between the chain link and the trashcan to add the exact same assignment to other classes. If you only have one class though, that option won't be there.
6. This is what the assignment will then look like. You can add comments that the whole class can see. You can also see how many are done, not done, and when it is due.
