I set this up for a personalized touch to my 3rd Grade Math Expressions. I used Kahn Academy and LearnZillion videos. Each day a lesson was taught as a whole group and they were in charge of their pace with a deadline in mind. You can change the date of assessment. This self paced style opened my time up to help those who needed it and allowed students to be more in charge of their learning.
