How can I reassign the same piece of homework again?

If you’d like to re-assign homework that has already been assigned, just go to your student’s page and use the gear icon in the relevant lesson row (homework column). You will have the option to ‘Remove Assignment’. After removing the assignment you will then be able to press the + symbol (homework column) and ‘Assign Homework’. Keep in mind, the existing copy of the homework answers will be wiped. 

If you’d like to re-assign homework without losing the existing student answers, you can simply re-enroll the student into the lesson, close the classroom, and assign the homework again. You’ll be able to toggle between your student’s different attempts by clicking on the clock icon in the lesson history table.
